Compatible with MeFOTO Backpacker Air tripod (part number PMU25). Might also fit onto other tripods, since it is Arca-Swiss style
Almost identical to original metal part and fits Backpacker Air plate mount as well as can use the camera screw that comes with the official build plate. The plate itself feels reasonably sturdy when used with metal screw and on my testing it easily held my mirrorless. Do your own testing and use at your own risk.
The original plate has rubber pads at the top, so I modeled those also separately so you can print them in TPU and glue in place. If used without anything to add friction, the plastic plate tends to loosen and turn quite easily even if tightened. Bluetack works also.
Included with this project is a camera screw which is modeled based on the screw that came with Backpacker Air tripod. I've succesfully used this printed plate and printed screw to hold my mirrorless camera but only for static, upright load. I wouldn't use it to anything with more stresses. BEWARE: It is only a plastic screw. Use at your own risk.
While modeling this project, I designed a small tool to help in tightening the build plate. There are two uses for it, primarily it is for hand tightening the original camera plate of the tripod, which isn't really designed for hand tightening. Another use is to thread the screw (metal or printed) on to the printed plate, which tend to have some stiffness on the surface touching the plate due to spread.
