3D Printed Pencil Sharpener: Duck

 

Challenge: To produce something unique and functional that could house a pencil sharpener.

Background: We have posted about this project in the past, and there are a number of posts relating to the process in the past and also from earlier this year.    The concept or idea is for a print to be combined to work in conjunction with a physical object.  This ensures that the students measure, check and design something different using the physical object as the key element.

We also have been encouraging the students to consider the detail that can be produced with both the P1S and H2D Bambu printers as it allows clear details and shapes to be produced with a minimal amount of rafting.  

You can see the design top left and the photographs of the physical object in the following images.   The only rafting that came with the print was contained in the insert where the pencil sharpener was located.  This project was created by two students working in unison using the ability of Tinkercad to have two students working together collaboratively.  

Resources used to complete this print: Tinkercad App, iPad, Bambu P1S, Orange PLA.

Level of Difficulty: Medium.  This print required a number of elements to work in conjunction with each other.  The students concerned did not create the duck that was placed on top of the box as this was available and located via the main Tinkercad design page.

Size: The print measured 40mm at the front was 50mm long and was 30mm high.  The duck was 30mm high and 40mm long to sit on the top of the box.   This related specifically to the size of the pencil sharpener which the print and the project was based around.   If this was converted into a storage box or something with another purpose then the project would need to be upsized as a consequence of it.

Cost/Price: The print used 24g of PLA to complete the print and had 4g of PLA support for the inside area.  This gave the print the price point of $0.62c to produce the unit.

Timeframe: The print took one hour and six minutes to complete and had an additional six minutes of time for the printer to warm up for a combined time of seventy two minutes.

What we would do differently/Next steps for the students: The print works as a design however the pencil sharpener itself is not held in place by a shelf or by some form of addition to the print.  The print also could have featured a draw or another insert which could have been removed or adjusted.
