I printed on a Core One in ASA with 3 bottoms, 3 tops and 3 perimeters with 20% fill on a satin plate.

Parts required for assembly:

• 1x M3x8 FH screw to fix crank ball to crank arm, if using crank.

• 2x  O-rings approx 0.88od x  0.087th (dash 908 number) +/- 0.010 on the thickness should work fine.
