Camera filter step-up adapter on a lens

Camera Lens Filter Step-Up Adapter (M49 → M58/M67)

A simple step-up ring that lets you fit M58 or M67 filters onto a lens with an M49 filter thread. Should print without supports.

What you'll need

  • 3D printer
  • Lens with M49 filter thread
  • M58 or M67 filter
Suggested material: PLA or similar rigid filament. Threads come out smoother at 0.1mm layer height, though 0.2mm also works.
