Hey guys, Check this out. Apparently this scope is "3D Printed" for the Ultrafire WF502B. https://pinshape.com/items/9672-3d-printed-tactical-flashlight-mount-for-airsoft-paintball If this 3D printing stuff is for real, I would love to print a whole bunch of stuff Like my own 3d printed synthesizer keyboard. Does anyone here have experience with 3D Printing? Is it easy to do? Expensive?
