Lomography Challenge - Lens Cap + Bokeh Filter + Pinhole

grabcad

This design features a lens cap that can be set to the neutral position, while also allowing access to a pinhole function and two bokeh filters in star and crescent shapes with the flick of a small lever. The assembly is easy and can even be done using 3D printing technology. Simply adapt the internal shut off to your desired shape and print new variants as needed. The four screws used may seem excessive, but are the same as those found in the main housing. Positioning is achieved by rotating the side lever, which locks into place with an internal mechanism. Design tools include Fusion 360 and KeyShot.
