3D Printed: Pencil Sharpener Holder Challenge

 

Challenge: To produce an original 3D Printed design that would be suitable to hold a pencil sharpener.  Student is restricted to create an original design from scratch and not use an existing or pre-made print.

Background: We have attempted variations of this challenge before, where the students have been tasked with taking an object and building it into a 3D Print.  You can see examples of this here on our blog.

You can also see a version of this design which incorporates a VR/AR version and one that has various filters applied.

This design came out of the process while this student is a student from the junior school this student has proven consistently to be someone who has grasped the concepts and ideas of 3D Printing and 3D Printed designs utilising a variety of techniques and excelled with her ability.

The scale of this print is larger than some of the smaller concept ideas of this version are smaller than a students finger.

The 'Dog' themed design was an original for the student.

Level of Difficulty: High - there are a number of component pieces that need to work in order for this print to be considered a success.  The legs need to balance, the tail needs to be feasible and the facial features of the dog are particularly important.  While importing many of these aspects would have been possible such as previous examples here, in this example we wanted the student to design them for herself to ensure that they were unique and she pushed herself with the design concept and idea.

Size: The print measures 140mm in length, was 50mm wide for the majority of the base and 80mm wide with the ears.   The design was 40mm high for most of it.  While the dimensions of this print is rather large it was intended to be this way.

Timeframe: This print took four and half hours.  Given the dimensions that were expressed above there was little that we would do to reduce or increase this time.  There was limited 'rafting' that took place at the base of the design.

What we would do differently/next steps for the student:

The student is happy with the overall design, aspects like the tail but she felt that the details in the face, which is conceivably the hardest to reliably create, she has stated that she wants to develop this particular aspect of the design further to make sure that it reflected a design that she was happy with.    Once this first print was created she felt she could have included additional details into the print to ensure that it would hold extra material such as a USB stick or a pencil.  Usually students are content with their prints, this is an example when a student wants to spend time and care to create a print that she is happy with. 

3D Printed Junior Christmas Projects Summary

 

Two copies of a basic Snowman design, created by a Y3 student.   Features oversized and exaggerated features and large loop in the head for attaching to a tree.  

This design was completed independently by a student in their first year of TInkercad designing using the main interface, selecting a predetermined snowman and then manipulating the design to add the features.

A small thirty minute design and print which was 40mm high.  Printed in metallic (shown left) and marble PLA (shown right).

Left another snowman - this was created again from the main Tinkercad interface.  The student used the top hat to add a whimsical feature to it.   The student also wanted to include an 'M' for their name on the base of it as well (which can be seen in profile).

This design was completed independently by a student who is also Y3 however has shown an aptitude to create and design using Tinkercad.  They were able to brainstorm the idea come up with the design, complete it all and submit it for printing in under thirty minutes.  

The print was completed in forty five minutes and is 50mm high to the top of the hat.   

The print shows an example of what can be created using a rainbow or metallic PLA which created the stripes that can be seen.   As we have noted on this blog we have opted not to spray paint the design further with any of these designs.

"Elf on the Shelf" original design.   This student was inspired with and then worked in conjunction with the student who was working on the Christmas Angel.   The student has used a series of original objects and designs that are available from the main Tinkercad interface.   By manipulating and altering and adjusting the basic shapes that are available an "Elf' was developed.

While the ring was inserted to allow the design to be hung from a tree it also had a base created that allowed the design to stand and be placed in a variety of locations.  The student wants to focus on an issue of redesign, related to the face of the creation as the definition the student considered not completed.

The design was completed using the metallic PLA print took two and a half hours to print and was 70mm high with a 40mm base/wide.   Other than the facial issues as noted the student is not intending to redesign this print.
