Atari Tempest spinner knob

prusaprinters

This is an accurate clone of the real Tempest spinner knob that will fit onto the “Arcade Spinner for Arcade1Up” encoder. The hole will slot right over the spinner body's shaft and will either pressure fit or you can hold in place with a bit of double-sided tape. There is a side hole for using a grub screw but that wasn't needed.Print in the same orientation as you would use it.Note: This doesn't have the same mass as the metal knob included in “Arcade Spinner for Arcade1Up” or the original Tempest spinner, so you don't quite get the same feel, but you can print with higher % infill to get a slightly higher mass.
