This is a camera mount quick release system for small inexpensive tripods that lack this functionality. Also compatible with quick release plates for the MeFoto Backpacker and Roadtrip tripods. NOTE: see entire pictures by viewing full screen.
This little gizmacchi utilizes an eccentric cam (actually a logarithmic spiral) to clamp the mounting plate securely.
I plan to use it to mount my cameras interchangeably between my big tripod and my Gorillapod.

0.20 mm layers
33 - 50%
There is a lot of force transmitted through the cam and the bolt (Panhead 3mm), so hi infill on these parts is probably good. My first version used 25% infill and the 3mm lock nut turned in the nut trap. The panhead allows for precise preloading of the cam tension, and I recommend that it be as tight as necessary, as loose as possible. Friction will hold it all together in use.
You want an 1/8 - inch drill bit
The cam turns on a 3mm bolt. Bore out the holes in the cam and in the body of the QR with an 1/8 - inch drill bit. Preferably, slowly, and by hand.
How I Designed This
Designed in the Schlaboratory..
Using good old Tinkercad with OpenSCAD for the logarithmic spiral render. See sources.
Get thee thine hardware!
You will need the following:
3mm panhead machine bolt, 15mm length
3mm lock nut
1/4 -20 flanged nut for tripod attachment
1/4 - 20 slotted machine screw for mounting plate, length to fit camera mounting hole.
