Find someone to print it for you. There are even services you can find that will print and ship whatever you can design. If my printer were setup is offer to help myself. Alas I'm probably two weeks out to being able to print anything.
figured I would update this thread as well. Messed around with a bunch of designs over the past week. really wanted to keep my wood forearm so I printed a rail so I could attach it and also added a barrel band with pic rail.
