3D Printed iPod Box - Delux

Above: Box with rafting still attatched
Challenge: Student wanted to create an original project as a storage box for his iPad.  He was challenged to come up with 'next level' additions to the design to incorperate new features that had not been previously created in the series of boxes and storage items being created in class.
Background: Student was responsible for the Mothers Day Box in this series of prints, featured in detail on this blog.  He has mastered the drop down lid for 3D Printed boxes.  He is a student who is nearly ten years old.  He is using 3D Printers and projects for the first time in class this year.
The box lid and handle
Level of Difficulty: High - for a students design on this machine this is about as challenging as it can get.  A basic box design incorperates a number of additional features - a internal wall to assist storage, a hole in the base of the box to allow the iPod to be charged when the box is closed, and a drop down lid with a lip that sinks down into the box.
Size: 19cm long, 8cm wide and a height of 8cm.  The lid was slightlty smaller with an internal lip the required the removal of rafting.
Timeframe: The main box was a twelve hour print, the lid was six hours. 8mm nozzle as detailed previously.
What would we do differently: The student concerned has previously mastered sinking lettering into the base of the box or object that he has created to personalise them.  In this instance he choose not to do this however it would have been a simple matter to include this.
Feedback from the student: The student who created this project was asked to talk about it and show the object which is the video that follows. (This video was informally shot by students in front of the green screen in our hall, this screen is a painted wall 8m across, 7m high and a depth of 2m from the green carpet tiles that come out from the wall)

Auroa Primary Technology Projects 2017

These projects are not directly 3D Printing Projects - they are showcasing some of the technology that students who are 12 and 13  year olds can complete at Auroa Primary School.  They have one Friday a week for three quarters of the school year where they

Previously we created speakers for 3D Printing that were a major project in 2015.   These speakers required 100 hours or so of 3D Printing to print the feet, handle and speaker covers.  For 2017 our students project was to produce these speakers as described below: the intention is the speakers will integrate some form of 3D printing accessories but students at present have laser cut the speaker from wood.

This video is a staff member who created an original Pinball table which was themed by the school with the voices and images of staff members. This is a personal project that he created on his own which he decided to share with the school, with the school looking to eventually have the students develop their own version of this table featuring themselves.

3D Printed Edison Robot Box - V3.0

Challenge: The Edison Robot is delivered in minial packaging, a simple fold out cardboard box that is designed to be disposed of once the robot begins being operated.  One of the issues discussed with the students was ways to transport the Edison Robot (which requires to operate just batteries and a programming cable).   The Edison Robots are high use items so we were looking at designing a way to transport them easily from location to location within the school.
Background: As mentioned above.  We have a set of robots that are high use items that are required for use all around the school in different classrooms.   The idea was a way in which we could have students take the robots safely (although they are very durable) from location as needed.
Level of Difficulty: Medium - the design was original however variations of this design have been mastered by the students Y5/6 (nine and ten year olds) in my classroom - however this is also a purpose built design from scratch.  
Size: Length 25cm and height of 15cm.  This box was created with a depth of 7cm.
Timeframe: The box itself was a twelve hour print.  The lid was eight hours.  The nozzle is set at 8mm which is intended to significantly speed up the printing process.
What we would do differently: The box lid was created as a by-product of another print.  There is not a specific area or storage space for the cable, although this programming add on is not always required when the robots are used and the batteries are preloaded into the machines before a class uses them.  While the lid fits perfectly with the box the handle is not the most practical for the students to use to carry the box (most lift the box from underneath).  The idea has been floated for a latch of some sort to allow the lid to remain in place, or an adapted handle that would make the carrying more practical.

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.
