I designed this in Solidworks so that it could be used with a PA ring (works with captive ring) or Steelworxx titanium hasp lock. I am still working on some more designs for lightweight on the go devices. PTEG seems to work well and have plenty of strength, also looking at printing in ASA.
I am still adjusting the model to reduce supports and have the ability to customize diameter, piercing size. Also testing strength with PTEG. Right now I have it designed to work with the Steelworxx titanium hasp. The lower support bar might become customizable also depending on piercing ring size.
I’m interested as well… have a new PA so it’ll be a bit before I can go back in to the cage, but on the lookout for something “shaft only” and lightweight.
I’d love to see where you at on this. Would you consider sharing the STL file so we can test it and share feedback?
