Prototype for an Iron Man cosplay I'm working on. It's for the Mk 6 Forearm I'm working on. I used filament as axles to hold it all together.
The design manually opens and closes, but still needs more work before the servo can automatically close it.
Edit Aug 22, 2019 - Design improvements, but progress will go on hold until frame for the forearm is done.
Discussion continued on theRPF forums:
Depending on your printer this could be a tight fit. Consider using an exactoblade to clean up some holes and edges. Use bits of filament to create your axles.
