M3 Toggle Latch High Performance.

thingiverse

Same drill footprint on both sides, Included two rigid stencil to drill holes on whatever you want use it. "lost" is sized just as lock. "Seal" has a 1mm more of clearance between the fixes, intended to press rubber seals. M3 screws all around. Includes STL for print all at once, But i recommend print the Arm alone, to have best print quality. and the best performance. Designed to be way more reliable than the original designs. (original fails before 5kg of lift) I recommend don't trim any part of the assembly, is this way to get some performance with plastic, on a application usually is full metal. The HP one is way more strong, actually is tested to lift more than 10kg. (PETG)
