POV Clock and Stand

thingiverse

This is a stand and electronics extension to the POV Clock designed by snug. The stand part is my first ever 3D design. Printed Parts ------------------ As well as the existing parts from https://www.thingiverse.com/thing:1098018 POV_Clock_Electronics.stl POV Clock Stand.stl Use 2 x 15mm Brass or Nylon Stand Offs for the top two screws. Use a 3mm tap to tap the two holes in the stand.
