Created an action camera mount for my Sony action cam.
Things you need to purchase:
1) One: 3/4" PVC SCH-40 pipe. Mine had a 1.055" OD and 0.80" ID
2) Four: 1/4-20 x 2.5" hex bolts
3) Four: 1/4-20 nuts
4) Swivel camera head. Mine happen to come with M4 thread to mount so i bought a M4x20 hex bolt to thread it on.
The "Flat Bracket" and the "Inside Washer" need holes drilled in them afterwards for the threaded portion of the screw. Didn't have a good way to get those holes in there without supports.
Most of the STL's will probably have to be flipped around before printing. Just use your wisdom for orientation :P
Bolts and nuts press fit into the parts. Oh, and the posts for my headrest measured 14mm in diameter. Other than that, just drill holes where necessary, mount, and go!
**Update: created another way to hold a Sony Action Cam
flip STL to print correctly.
