I have some 3d printers at work and was hoping to get some dimensions to work on a 3d print before attempting to have some CNC machined. It would be a lot easier if I had something to work from. I'll have to see if I have any extensions that are close to working either from my seecamps or rm380's.
I'd like to have something that works on the r9. Perhaps the Kahr extensions might be close.
