DIY - 3D printed hood mount protector ring for Voigtlander 50mm F1.2 Nokton Leica M mount lens

 Today I'm sharing freshly designed 3D printable hood mount protector ring that perfectly fits Voigtlander 50mm F1.2 Nokton lens in Leica M mount.

Voigtlander 50mm F1.2 Nokton lens in Leica M mount has 52mm filter size. The geometry of hood mount ring looks similar to few other lenses, so the ring should also fit:

  • Voigtlander 35mm F1.2 Nokton III M mount
  • Voigtlander 40mm F1.2 Nokton M mount

The protector ring I designed earlier for Voigtlander 35mm F1.5 Nokton lens was easier to make due to more simple shape of hood mount and flat base. For 50mm F1.2 lens it is more challenging due to ring bottom edges are 2.5mm thick. I decided to cover that area with just 1mm thin layer to minimize RF view obstruction.

Protector ring is mounting then locking at place with CW rotation like mounting regular hood. I printed one with PLA material, so the ring is slightly flexing but feels robust enough once mounted on lens (thanks to very durable brass material of hood mount ring).

Main features of protector ring:
  • completely covering shiny chrome ring making lens all black and more discrete
  • protecting hood mount petals from accidental hits when hood is not in use
  • has sleek minimalistic design to minimize rangefinder obstruction
  • is easily mounting on with clockwise rotation like mounting on lens hood
  • has 54mm inner diameter allowing 52mm filter to be mounted on lens
  • easy 3D printable with no print support required thanks to angled inner walls

Ring is covering chrome edge with aperture marker dot. I've hand drilled shallow detent on plastic ring surface and added a touch of liquid chrome paint.

NOTE: the radial position of ring remains same after mounting in CW direction until it stops moving, though there is no any type of locking that position.
