Pinhole body cap for Micro Four Thirds camera

thingiverse

This is a custom MFT body cap with an integrated holder for a 20mm disk, ideal for creating a precise "pin hole" aperture similar to those used on the popular Easy35 pin-hole camera. Initially, I envisioned printing this design without supports from the print plate. However, upon closer inspection, it became apparent that significant cleanup would be necessary before utilizing this design effectively. In fact, my primary goal was to test pin holes for use with the Easy35 camera, and I decided to create a mock-up using MatterControl as a proof of concept. Fortunately, this prototype works seamlessly on my trusty Olympus OM-D E-M5 camera. It's essential to note that the cut-out in the rim must align perfectly over the pin that the camera uses to detect whether a body cap or lens is attached. I've also been experimenting with creating precision pin holes from Aluminum soft drink cans.
