Picatinny rail extension for BTPR build. The zip file include the rail, pins and print orientation. I'm currently working on these files making all the gun modular... for future releases.
I printed the part with these settings but you can tweak it to fit your needs.
layer height : 0.15
tree supports
bed adhesion : brim 8 lines
walls at least 6.. this is a structural part.
infill : 99% .. you can use >50% but I haven't tested it yet.
nozzle: 230
bed: 60
top/bottom layers: 3

I will release the other files as soon as I'm done with the upgrades and testing.

Happy printing!
