Need a different size than what I offer here? Please just reach out and ask. I can make custom sizes very quickly and easily. Need to replace a C-clip on your lock? Or maybe you're doing a lot of assembly/disassembly of a particular lock (progressive pinning) and don't want to hassle with the metal C-clip. These 3D printed C-clips might be just what you need. These clips will hold the plug in the lock just as well as a metal clip, but are so much easier to remove because they can flex. Sold as 5 packs. There are two sizes offered here currently: CLIPA-0001 10.5mm inner diameter 1.8mm thick Known to be compatible with the ASSA 600, and probably many other locks. CLIPB-0001 11.7mm inner diameter 1.8mm thick Known to be compatible with the ASSA 700, and probably many other locks. CLIPC-0001 10.5mm inner diameter 1mm thick Known to be work on many Euro cylinders. Attribution of this design goes to eschlenz (of 44 Delta)
