our Bitcoin money. But, before reviewing the final product, below we'll discuss a couple of the pieces.
Snap ring- The snap ring fabrication was completed between last Friday, Dec. 7th and this Monday Dec. 10th. We did not encounter any of the difficulties with burning that had been occurring earlier the week before. To complete the fabrication as quick as possible, we utilized three shoulder bolts acting as shafts to allow us to place the bolt inside the snap ring.
Stockline line overmold- This piece was completed last Friday, Dec. 7th, and has a sleek, elegant look. While fabricating, we were tinkering with he shot size and pressure profile because short shots were occurring. However, we noticed that the orientation in which we placed the stock line into the overmolding core affected how the filling occurred. We experienced flashing and short shots because of this. Given that the stock line is not an even design, this can explain the discrepancies. Furthermore, we still continued experiencing flashing along the outer diameter of the are where this piece snaps in to the snap ring. This then would not allow the pieces to snap.

Now, finally, images of the yo-yo in separate pieces and the assembled yo-yos can be seen below.
Thermoforming- We had some issues with the original design of having to half that would fold and hold together via a series of positive/negative holes. the issue encountered was that getting the holes to work was not working. Thus, we pivoted to a Duncan yo-yo inspired design of casing, but with our own creative flavor. Below you can see the old mold (greater in length) to the new mold (with a dome life feature).
Furthermore, here is the finished thermoforming casing that is held in place with the use of papers.

We would like to thank the 2.008 staff, Prof. Hart and Dr. Wendell, as well as the TAs and the shop staff for helping guide us in this journey. We learned a great deal and have a fun yo-yo to show for it.
