More information
This is a tool for removing the roll pin that retains the ejector pin in an AR-10/LR-308 bolt.
(See https://www.thingiverse.com/thing:3270414 for an AR-15 remix by kombayotch.)
The concept is roughly based on the $63 version sold by a large distributor. Theirs, of course, is made of metal, and does both AR-15 and AR-10 bolts. I thought it would be more fun to make one, and since there wasn't already one on Thingiverse, it would be a useful addition.
This is configured for printing with ABS, and accounts for the shrinkage factor. I chose ABS because I already had it loaded in the printer, and I felt like PLA might be too brittle (perhaps not, I haven't tried it).
The metal bits that are required are a 3/8" x 18 nut, and a 3/8" x 1" x 18 thumbscrew (best), hex-headed bolt (OK), or screw (ick). The included cap goes over the end of screw threads, and can be affixed with a dab of silicone adhesive, although pretty much anything should work well.
Holes are provided for #6 sheet metal screws, should there be a desire to attach it to a piece of wood for additional stability.
