Picatinny to Arca Swiss adapter plate

thingiverse

Simples - picatinny rail on top, arca swiss profile on the bottom. Put a scope mount or whatever attachment you want on the rail, and mount the whole thing on your Arca-Swiss tripod head. If you're wondering about the little rounded slot on the bottom, it's there to accomodate the safety catch on my tripod head (which prevents plates from falling off when you loosen the locking nut and slide them around). Due to the length of the rail, there might be some flex, but it should not break if printed properly, even under extreme mishandling. I recommend 2mm walls (shell), 50% infill with gyroid pattern and PETG. Turn the fans off if printing in PETG.
