I am an inventor and designer with 75 US patents. I am always looking for ways to improve things. I own an Olympus Pen-F Digital and was looking for a grip that was strong, comfortable, able to add a hand-strap to and light in weight (37g). I went through over 30 iterations and prototypes before finalizing this design.

Here are a few reviews from past purchasers!

The Camera Grip for other cameras can be found in my eBay store.

As is normal for FDM 3D-printing; there may be gaps, protrusions and imperfections in the surfaces of the print (see photos), but none of these imperfections will impede the use. I try to sand off any anomalies that may interfere with the grip. If I miss some, a file will easily smooth the area.

Always use a camera strap to prevent accidental dropping of your camera!
