These early prints were done in 2013 but with all the recent hype about 3d printed Ruger 10/22 Rifles being printed we wanted to confirm that yes its possible and we’ve done it before.
The CAD files for the Ruger 10/22 rifle receiver are in the latest Fosscad Megapack 4.7. An STL file was created directly from the solid model (IGES file) and was printed using Bolson black ABS (Below). Haveblue printed the receiver upside down so that the interior didn’t need any support material, and thus would provide as good a finish as possible. If you’re looking to do this kind of project, make sure your parts are printed from an iso certified machine shop to ensure high quality.
The hole in the receiver was slightly undersized (not unexpected, and better than being oversized).
Tapping the barrel clamp holes with 12-24 threads (thanks to the blueprints at fireamfiles.com) as well as the stock mounting screw hole in the front tang.
Test installation of the barrel itself, which tightened up nicely, but I noticed that the barrel would visibly cant downward as I tightened the clamp screws. Still not perfect but a good start.
There wasn’t enough clearance on the front counter-bore, and the back of the barrel was catching on the top front edge of the receiver. So it was back to the boring head to enlarge the diameter on the mating face slightly.
A test fit of the bolt – it was a tight squeeze to get it past the rail on the inside right of the receiver.
The trigger pack would fit right away. The rear wall of the receiver in the original IGES file may be a touch too thick. The rear was thinned out by about 0.030? until the retainer pins went through the receiver and trigger pack (The holes in the receiver was reamed out already at this point).
Finally all the internals fit and it could be dry fired.
The receiver assembly would not fit in the wood stock immediately. There is an extra relief cut on the original receiver at the interface between the tang and the receiver front. The original IGES file does indeed have this relief cut, but SolidWorks removed this feature. This may be due to the fact that the STL file was not directly exported from the original CAD file itself. Simple fix machining out the issue.
The barreled action fit just fine in the stock, and both the 10 and 25 round Ruger magazines fit, though perhaps a little more loosely than desired
Test fire with a 25 round magazine and in ran nicely. There were a few feed issues. Speculation is that the fitment of the magazine could be to blame, as it seems that the front of the magazine is able to tip down a little too far. Both magazines are also absolutely brand new (this was their first usage), and 10/22 magazines operate better after an initial break-in period.
