Shield PIP Fidget

I made this PIP fidget with a partner! Below is the link to his printables page:

Problem Statement:

Using sketch offsets and extrusions, and cuts, create a telescoping fidget of any desired shape.

Activity Overview:

There were some constraints we had to follow, and they were as follows:

• The sketch begins with a constraint box that is 18Cm by 18cm at its maximum
• You can choose to do a large fidget or a nested array
• The sketch must effectively demonstrate and efficiently use dimensions, relations, and offsets
• It isn't required to fully define your sketch, although it will be very helpful
• Finally, there should be 0 error messages in the sketch

My partner and I chose a shield as our design. We both liked the design and thought it would be really cool to print and turn it into a fidget.

Steps:

To do this, here are the broad steps we took:

• We found an image and put it into SolidWorks, and fit it in the constraint box

• We traced the image in SolidWorks

• We did a series of offsets on the original outline of the shape

• We did a series of cuts and extrudes on the offset shapes

• Then we mirrored everything

Design Changes:

In total, we made 3 changes, and they are as listed below:

After finishing our CAD, we realized that the outer ring of our fidget wasn't thick enough, and if you squeezed it would bend, and it was more susceptible to breaking, so we thickened the outer layer for more support.

Before Thickness:

After Thickness:

Our other change was when I printed it for the first time; the layers of the print were peeling off, and all of the shapes were falling out of the fidget. This is because one of the filaments I chose was pretty old, so it wasn't good, ruining the whole print. To fix this, I chose a new filament with a similar color and reprinted it.

Our last change was an idea given by another student; his printables page is below. The idea was to mirror the front face, not the back face, of the first half of the fidget; this provided more structural support and made the fidget more durable overall.
