3D model description

Large primer load arm for Hornady LNL AP, this is an untested design but should work fine as it is the same as the small primer arm with and enlargement for the bigger primer. I'm not set up to test it right now, but getting it out quickly as I've had a few requests. Let me know if it does not work for you. This not meant as a replacement for the stock arm, rather a stopgap part to keep you going until getting a replacement. 11 cents to print this part in PETG, about 25 cents for PC. Takes about 45 minutes to print, at the recommended resolution
Send me likes or tips if you like my designs, it takes several hours to design each one, although the primer arms may look simple the perimeters are not they are from an imperfect original design from Hornady and needed a lot of tweaking to work with a 3d print.
