About this 3D model

Print settings: Print the model rails down! All other info and assembly instructions can be found on py2A. This is a modified design that adds the second locking block pin that py2a claims is unecessary. However, if you want a frame that can hold up to many rounds and +p ammo, then you definitely need that 2nd pin. Layer Height: 0.12mm Print Speed: 60-80mm/s Walls: 10 walls (You want the model to be as many walls as possible) Infill: 100% Supports: Tree supports touching build plate only, support x/y distance: 1.3mm (this avoids cura creating supports for the stipple)
