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)
