The Quark, a Yo-Yo

This is The Quark, sequel to The Ork and The Dork.

It uses a 4mm x 20mm stainless steel shelf pin as the axle. These are the ones I used. https://www.amazon.com/gp/product/B0D1VF3P4C 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.

If you print it and it doesn't come back up add a drop of lube or rub some chapstick on the end of your string and after a couple throws it will work just right.
