Nerf Vortex Disc Holder Attachment

I love the dart rack attachment for other nerf guns since it's just about the only practical thing to put on the tactical rails. So I decided to design one for holding vortex discs.

The third photo shows all the prototype designs I went through to get to the final design. I have my printer set to overextrude a little bit, but hopefully the fit will be as snug when printed on other people's printers.

The screws I used were #4 x 1/2 IN.
