Four Thirds Rear Lense Cap

thingiverse

This is a Rear Lens Cap designed specifically for Four Thirds lenses, not Micro 4/3 models. I've noticed that cameras like the Olympus E-3 use this type of cap, whereas the Pen and OM-D series employ Micro 4/3 technology. I've tweaked the design to make the exterior slightly smaller than the original, which seems to work just fine and reduces production time and materials needed. If you prefer a larger version, feel free to modify the provided CAD file to suit your needs.
