The file 'Hollow Clock 2 – Silent And Smooth 3D Printer Model' is (ino,stl,blend) file type, size is 1.7MB.

Summary

  • Silent and smooth : stepper motor version of "Hollow Clock", https://www.thingiverse.com/thing:4747403
  • Easy operation : super-easy time adjustment
  • Easy print : printable without supports (except optional cover.stl)
  • Easy assembly : gears can be set by just sliding in
  • Cheap : used stepper motor is very popular and cheap (around 3USD with amp circuitry)

A bit smaller than original "Hollow clock" (rotor diameter : 200mm vs 160mm). Now it has no air gap between rotors.

Update Feb 24, 2021

  • Arduino code for stepper motor control is improved. Rotation is a bit smoother than before, with 8-phase control.

Update Mar 3, 2021

  • Cover for the rear parts (stepper motor, circuits) is added. It needs support to print.

Update Nov. 21, 2021 : "Hollow Clock 3" is released.
