A coworker pointed out that McMaster Carr has CAD downloadable for many fasteners and other items. Armed with this time, I grabbed a STEP file for an M4-0.7 6mm socket head screw in blazing speed. 

Otherwise, not much to report. I have mirrored over all the components on the left side of the feeder to the right side, and will now be working on connecting both halves to a shared hopper. 

After the hopper is designed, I'll be adding some pipes to provide primary structure, and a few gears that turn with the feed wheels for aesthetics. Then it will be time to move from mechanical to electrical. 

Roadmap:

1. Shared hopper
2. Pipe primary structure
3. Gear aesthetics
4. Shift to electrical work
