T-Mount(M42) to Canon EOS Adapter
thingiverse
I just bought Kelda lens 500mm f/6.3 from ebay. The lens look a lot like Samyang 500mm. However, there are no canon-mount provided. So I adapt the EOS-female side from "Canon EF Extension Tube v1 - 50mm by martinmunk" and create T-Mount by using "T42 to Canon EF-S lens Adapter (Work in progress) by Bootdsc" as a mold. I print it with Prusa i3 Height 0.2mm Nozzle 0.4mm No support is require. 43 minutes and it ready. Thank to martinmunk and Bootdsc for your great work. Thank.
