Barrel Mounted Picatinny

I made this barrel mounted picatinny for my Keltec Sub2000 9mm carbine, but it will fit on any 16mm barrel rifle. You can also customize it to fit any barrel size you want on TinkerCAD. There is no picatinny on the top because the rifle folds vertically in half for storage.
It fits on the barrel just between the front sight and the hand guard.
Not sure if the screw and nut will be able to print, I threw those in just for fun. You will be better off purchasing a the accompanying screw and nut.
The holes are sized for M3 X .5mm nut and a M3 14mm long socket head screw.
Good luck and enjoy!

UPDATE: The mount printed well in the orientation shown with exception to the bottom edges of the picatinny rails. Even with support, they were stringy. You may have to experiment with printing orientation.
