Manfrotto 200PL plate to Arca-Swiss dovetail adapter
A block that screws to the bottom of a Manfrotto 200PL or 200PL-PRO quick-release plate and gives it a 38 mm Arca-Swiss dovetail, so a camera that lives on a Manfrotto RC2 tripod head can also drop into a Peak Design Capture clip or a SmallRig Arca clamp. The 200PL plate is about 52 x 42 mm, so the adapter matches that footprint at 55 x 42 mm, 12 mm tall, with a 6.5 mm through hole for the 1/4-20 camera screw, a 12 mm hex pocket for a spare nut, and 45 degree dovetail flanks with 1 mm safety stops at each end. Print it flat in PETG at 100 percent infill and 0.16 mm layers so the dovetail edges are clean.
Switching plates every time you change heads wastes the moment. Describe both your plate and clamp in SpeakCAD, preview the adapter in the browser without paying, ask for the reverse combination in the chat and download the STL.
Model an adapter block 55 x 42 x 12 mm that bolts under a Manfrotto 200PL plate with a 6.5 mm through hole and a 12 mm hex nut pocket, and presents a 38 mm wide Arca-Swiss dovetail with 45 degree flanks and 1 mm safety stops at both ends, 100 percent infill.
