Parameteric Minimalistic Tracker Disc

prusaprinters

I wanted a dead-simple point tracker without bells and whistles that can be printed in a few minutes.The following can be configured using the OpenSCAD customizer:Number of rings (2-digit and 3-digit STL included)Font and font sizeDepth of the digits (can be negative to have them stick out instead)Clockwise/Counterclockwise directionHeight of the disc and width of the ringsSize of groove between ringsOverlap between rings for the internal notchTolerance between ringsIn my experience the inner arrow ring needs some extra tolerance because there is less leverage to separate it after printing. 0.3 mm between digits and 0.4 mm for the arrow ring worked well for me.Recommended Settings:Disable supportsRandomized Z-SeamIroning for the top surfaceThere is no snapping for the numbers, so this also works as (bad) fidget-spinner.
