3D Printed Edison Robot Box - V2.0

Edison Robot Case Version 2.0
Challenge: Student had designed the previous print in this series as a stand/box for an Edison Robot, his original design featured a single compartment for the batteries and the coding cord, and the robot itself was too big to fit into the box.  These issues were intended to be addressed in this improvement.
Background: Following feedback from staff over the first print the student was challenged to make improvements on the design to make it more user friendly.
Level of Difficulty: Medium - this is an update of a previous print that has worked, but this student is making adjustments with the intention of making improvements.  The original design had a combined battery and cord space and he wanted to seperate the two into distinct areas.  In the first print/design this area was a combined space and the robot was not able to fit into the space so it was tilted, the student was looking at a way of stacking multiple robots in a space with all thier equipment.
Size: Length 16cm, width 10cm and a height of 3cm for the sides.
Timeframe: Seven hours to print (8mm nozzle).
Process: Unsatisfied with the original design the student modified it in Tinkercad to make the changes that he thought was required.
What we would do differently: Although it isn't perhaps obvious from viewing the photographs supplied the batteries were originally intended to be standing up in the space above occupied by the connection wire - however this space was only able to have three batteries standing in the area vertically which was the intention.  The student has indicated that he can make improvements and will redesign the print accordingly.   He has been asked to think about ways in which multiple robots can be stored and the boxes linked together and also the possibilities of individualising each box for ease of location of specific robots (as we currently have a dozen at our school).

3D Printed Edison Robot Box

Edison Robot in storage with additional items.
Challenge: The Edison Robot comes as a low cost pre-programmed Robot for use in the classroom/education.  The emphasis on packaging is minimal so when the device is unboxed it is ready for use.  It also comes with additional items that are required to run it, batteries and a headphone set.  The idea behind this design was to introduce a storage space for the Edison Robot where these additional items (and the robot) could be cleanly stored when not it use.
Background: Student had previously designed low level design and was looking to extend himself with something more creative and unique.  The school has a set of thirteen of these robots all of which have additional items that are required for them to run, the teacher concerned thought that the idea itself was excellent and would really help the storage of these robots.
Level of Difficulty: Low-Medium, the design itself was straightforward consisting of basic and common shapes with a divider in between (as shown above).  However the student already has ideas to increase the complexity of the design based on the prototype that has been printed.
Size: As shown a length of 15cm a height of 10cm and a depth of 3cm.
Timeframe:  Six hours to print. (8mm)
Process: Tinkercad, main interface then into Cura and then printed on an Ultimaker 2+.
What we would do differently: This was the first design and the idea was essentially a prototype, the student as the print run was being completed was already considering alterations to the design, either increasing the size of the space for the Edison, which at present in slightly smaller than the robot, as shown above.   The other consideration is to raise the depth of the sides of the box which currently are 3cm.

3D Printed Egg Cup

Eggcup with rafting holding beak in place
Challenge - Student was interested in creating a practical 3D Print that would have a regular use.  She enjoys eating eggs for breakfast and had seen the previous design of a Egg Cup.  She believed that she could improve on the design, and did so using the basic Tinkercad design interface.
Background: We encourage students at our school and in our class to create original designs that are practical and original.  If a design meets this brief then we take an opportunity to print it.
Level of Difficulty: Medium - this was designed from the basic Tinkercad Interface of which the chicken feet and beak are basic designs.  There was innovation with the hollowing out process and the sizing of the design.
Size: Width of 6cm, length of 6cm and a height of 6cm.  
Timeframe: The print took five hours -  the difference that this has made, the original design in this series was a nine hour print (both with a 8mm nozzle).  This was a more compact design as the original had wings and an extended beak etc.
Process: Most of the key features of this design were created using the basic interface options available on Tinkercad.  It was the students first original design for a Y6 (11 year old student) and as a consquence the student wanted to keep the design simple to ensure it was successful.  As per most designs here it was a process involving Tinkercad/Cura and then printing on an Ultimaker 2+.
What we would do differently: Nothing.  The design was a considerable improvement on the original, it was more practical, had better balance and served a better purpose.  The student was thrilled with the result and it would be considered an extremely successful print.

Y2 3D Printed Cookie Cutter

Completed Design - Rafting to remain as part of design
Challenge: Looking to engage a Y2 student in a project it was decided to use 3D Printing to involve him in the creative process.   The student was able to select the image for his 3D Print which was then converted with the intention of it becoming a cookie cutter.
Background: The process that was used for the project came from this site, with the steps described under the 'beginners guide to 3D Printing'.
Level of Difficulty: Low - the student was six years old, so the conversion of the SVG file for its import into Tinkercad was conducted by an adult as it was felt that the student would not be able to do so independently.   (It should be pointed out that he was not given the opportunity and probably could have done so with instruction).  If you look closely at the design you can see the top left hand ear of the cat is in fact slightly seperated, ideally the original design would have a slightly thicker outline to allow for a thicker print.
Size: Strictly speaking for a cookie cutter this is quite a big design being 10cm across and 20cm high.
Timeframe: Four Hours - again as has been repeatedly stated we are now using a 8mm nozzle.
Process: An image on a google search, converted into a SVG file for an import into Tinkercad.  This was then stretched from its original flat design into a shape that would allow it to be used as a cookie cutter.
What we would do differently: The rafting was delibrately left on this print to help with the pressing of the print into the cookie dough.   As noted the width of the design ideally would have been slightly greater width of it to make the design more robust, however the creator was extremely pleased with it, including as a reason the fact he could make really big cookies from it.

3D Student Printed Desk Organiser - Take Three

Design prior to removal of all rafting
Challenge - previously on this site we have detailed the design and creation of various desk organisers for students to use to keep their stationary.  These have been individualised by the students and we were looking at an eight hour or so print time.  We also decided to encourage the students to look at producing smaller versions.  This item came out of this process.
Background: Student based her design on similar designs from other students in the classroom.  She focussed on individualising it by having her name sunken into the base of the object.
Level of Difficulty: Medium the student letter and font was made as part of the shape and the shape itself was oval.  Not all the letters were able to be sunken to the same depth due to the design.
Size: The student organiser was 10cm heigh with a base of 6cm across.
Timeframe: Four hours - this was halving the time for the larger pieces.
Process: Student was producing her first next design using Tinkercad following a name plate.  She was clearly influenced by this design in the series, however the size aspect of it made it unique.
What we would do differently: The students object was limited by what it was able to hold as a result of its size.  The lettering worked extremely well and the student was able to produce this independently.  As a consequence she was thrilled with the design and able to produce an object that she was proud of.

3D Printed iPod Case

Above - Box and lid together - prior to removal of the 'rafting'.
Challenge - Student who had previously completed the expected introductory tasks was looking to move towards creating more creative and technically difficult print.  He identified that he had an iPod that currently sat on his desk at home when not at use and decided to print a box to use for storage.
Background: Student created the original idea from scratch and as a consequence designed it, measured it and throught about the process and the end product.
Level of Difficulty: Medium.  This was created by a nine year old student however it required a number of compartments and details that required specific measuring and designing.  It was a completely original design from start to finish including a 'drop in lid' and cosiderable rafting which needed to be removed in stages.   The lid and the box were printed separately due to their size.  There was inspiration from this box.
Size: the base was 15cm wide, 10cm across with a depth of 5cm.  The lid was essentially slightly smaller than this so it could drop down into the base.  
Above Viewed from above the compartment visible
Timeframe: Due to its size being slightly smaller than the Ultimaker 2 build plate both major pieces were printed separately.  The lid was printed in an six and a half hour print.   The box was more detailed and required ten hours.
Process: Inspiration came from another student in the classroom with thier 'Mothers Box Design'.  There were elements of that design in this, such as the drop in lid.  The student has previously used Tinkercad to produce basic classroom designs and was looking to stretch himself with a more complex design that would also have a practical use.  
What would we do differently: There was not a a signature/name built as part of the design which is something that could have been included.   The student spoke afterwards and it was suggested that there could have been an insert designed into the box that would have allowed a charger cord to have been plugged directly into the box or a dock option to hold it.  The student himself was extremely pleased with the project and the execution of it.

3D Printed Student Desk Organsier

Above: Print on base plate with rafting
Challenge: This student was looking to expand his use of 3D Printer by creating something that was original and also had a practical use for him in the classroom.  The student in this case was a Y6 student who was 11 years old.
Background: Student was inspired by similar prints from other students in this series.  He was looking to ensure that the print was original and had his own spin on previous designs.  He adapted the singular approach of previous desk organizer to include a central cylinder and six additional smaller cylinders for the holding of stationary.
Level of Difficulty: Medium - a basic design in this series has seen a singular cyclinder model, this design improved on the basic design by incorperating additional storage as seen in the pictures.
Viewed from above with storage visible
Size: 15cm by 15cm with a height of 10cm.  The typical prints in this series by the students have featured a greater height however the student felt this design suited the purpose.
Timeframe: Nine hours (8mm nozzle) with a regular print structure.
Process: Designed in Tinkercad, with the basic shapes created using the main default design tools.  The design was then imported into Cura, the design and processing program for 3D Printing on an Ultimaker 2+ and then printed.
What we would do differently: The concept was an improvement on other prints in the series with the adding of additional seperate storage areas for a desk organiser.  Most of the previous designs had included the name of the creator sunk into the design as an insert, this design featured a 'block' at the front that included the students name.
