Rotating Filament Swatch Display

Reupload from Makerworld, made by TimothySt:

Adaptation of BradFTBT3D's great design.

I was annoyed that the display only turned in one direction, meaning once you miss the desired swatch you have to circle all the way around to it again. So I modified the bottom part and now it moves in both directions.

Original print instructions:

Print Settings:

• Top Layer Height: 0.20mm
• Bottom Layer Height: adaptive or 0.10mm (for smooth ramp)
• Top & Bottom Surface: Concentric
• Print top upside down
• Use Arachne wall generator for best results
• As designed it will only turn clockwise, mirror base to turn counterclockwise

For best turning:

• Sand the ramp smooth with 220 grit sandpaper if needed (and lubricate a bit)
• Put rubber feet on the bottom so the base won't spin while turning the top
