Post-processing:
DO THESE ONLY IF THE CYCLE ISN'T SMOOTH:
I suggested to file/sand down the inside part where bolt cycles for smoother travel. Also sand down the back claw part that locks into lower for easier disassembly of the replica.
Be sure to remove all the supports inside the design.
Tested with eSUN and Elegoo PLA+, Sunlu PETG.
SAFETY DISCLAIMER: Always wear proper face protection when playing airsoft, especially with 3D printed parts! Please be careful!
