CAD Updates

Over the past week, we worked on a few design updates to our yo-yo model. We decided to replace the supporting posts for the Compass Star (that were intended to keep it stuck in place so the Star doesn't spin when the yo-yo spins) with a press fit. This means that in order to secure the Compass Star in place, we will be using a press fit to secure it in between the yo-yo body and snapfit ring. This decision meant we had to:

1. Create a post on the upper surface of the Compass Star to support the needle. The needle is intended to rotate while the yo-yo spins, and we are using a slip fit to do so.

2. Create an "endcap" to place at the end of the post to make sure the needle doesn't fly off. The endcap leaves room for the needle to spin.

3. Change the geometry of the snapfit ring so it can snap onto the yo-yo body as well as hold the Star in place.

4. Change the geometry of the yo-yo body to add a lip for the Star to rest on.

Moving forward, we might need to think about adding notches in lip of the yo-yo body where the Star is intended to rest (and counterparts on the underside of the Star itself) to make it easier to place the Star in the correct orientation upon assembly.
