These are the 3d printed files for my DIY ballbar seen in the YouTube video:

STEP files are ready to be sliced. Print them in PETG.
BOM:
- 16mm ballbearings
- 10x3mm Neodymium Magnets
- Webcam: https://www.amazon.ca/gp/product/B07VL7BNLZ/
- Laser (You'll need to source this. Get one that is low powered as the laser is shining directly onto the webcam sensor). You'll also need to adjust the laser mount in the STEP file for the flexure to fit the laser that you use.
- Washers: S/S Flat Washer (A2) / M6
- lapping grinding abrasive. This is used to get a good fit of the washer to the 16mm ball bearing. (I used between 250-2000grit rock tumbling abrasive)
- heavy metal plate for the base to attach to. (I used a ½" plate about 10lbs in weight).
