This remix replaces the Kwawu Forearm part from the Kwawu NIOP Remix and will fit the standard bolt used for terminal devices used by prosthetists. It requires a threaded insert.
1/2"-20 SS Threaded Insert x 1/2" - Part# 91732A533
There are 3 files provided for this forearm part. If you print at 100% you can use the main stl file. If you need to scale it, use the "Scalable" version and subtract out the "Std Prosthetic Bolt.stl" for the bolt hole. That will make the hole for the insert the correct size.
