Optional Drill Use

This model was designed with the use of an electric drill in mind to respool the sinew onto the 3D printed sinew puller. The hardware I used is listed below. I used a soldering iron to set the inserts into the plastic. The hole is purposely undersized to allow for enough plastic to adhere to the insert.

Note: I used 4 walls when printing with the intent of adding inserts. This allows enough plastic at the hole for the insert to fuse into the model.
