How to make a name keychain

  1. Type the name (short names look best).
  2. Adjust letter height (10–15 mm), letter depth (1.5–2 mm) and plate thickness (2–3 mm).
  3. Set the ring hole diameter for your key ring (4–6 mm).
  4. Download, slice and add a filament change at the plate height for two colours.

Printing tips

  • PETG or PLA+ are tougher than standard PLA for keys.
  • 100 % infill and 3–4 walls make the ring strong.
  • Iron the top layer for a smooth plate.
