From Sickburn Yo-Yo Workshop:
“This is a doorknob shaped yo-yo, it actually plays very well, and is surprising for it’s shape.
It is a challenging print and you will need a well tuned printer and you may need to do a temperature tower first to ensure you have the right temp for the overhangs. It took me a few failures before I got the overhang right. Settings that helped me succeed:
- Enable dynamic overhang speeds
- Slow perimeters (30 mm/s)
- Extra perimeters on overhangs
- Avoid crossing curled overhangs
- Detect bridging perimeters
I included a 3mf file for MK4S MMU3 that has these settings in it for those with that printer.
It uses a 4mm x 20mm stainless steel shelf pin as the axle. These are the ones I used. https://amzn.to/41RypW. I recommend a tiny drop of super glue in the axle hole then the pin, then the other half with glue as well. If you want it to work well slice it to 54-60 grams weight. Honeycomb or cubic infill for best balance.”
