Description

What it's for

A 3D-printable watch case modelled on dive-watch proportions. Features a scalloped rotating-style bezel with minute markers, a fine threaded base for the case back, and integrated lugs for a standard watch strap. The inner cavity tapers to secure a movement, with a lip cut for a domed crystal.

Dimensions

  • Overall Case: 42 mm diameter
  • Inner Cavity: 41 mm base, tapering to 40.4 mm at the dial
  • Lugs: Spaced for a 20 mm strap
  • Crystal Seat: 41.4 mm diameter, 1 mm deep
  • Stem Hole: 1.1 mm diameter at the 3 o'clock position
  • Threads: 0.5 mm pitch, matching case back included

Print notes

The case back uses a very fine 0.5 mm thread pitch. This requires a well-calibrated printer and low layer heights (0.12 mm or finer) to print cleanly. You may need to scale the case back slightly on the X and Y axes depending on your printer's tolerances.
