Olympus Pen F to M42 Adapter

An adapter for Olympus Pen F half frame camera bodies to take M42 Lenses, takes into account the flange distance so should focus just fine. Should work with most m42 lenses, has an additional step inside to press down the aperture blades in case your lens doesn't have a manual step down option. Since Pen F lenses have the release button built into them the adapter is just a friction fit onto the camera, it's held my larger lenses just fine but be careful to make sure to not let it unscrew itself.

I printed using a .6 nozzle so should be fine with any nozzle, just make sure the m42 threads print good. Designed not to need supports as well.
