airsoft glock/aap01 m4 adapter

thingiverse

IMPORTANT: only use supports on the build plate, and paint some inside the button latch area. you do NOT want supports on the inside of the air tube. you'll also want supports under the bb tube. print with at least 4 walls, 5-6 is better. infill doesn't matter, i used 25%. obviously print each part with the flat part on the build plate. glock to m4 mag adapter. works on WE glock mags and AAP01 mags for sure, i don't know if it'll fit elite force/VFC/TM glocks. i printed in overture pla+, works and feeds fine, doesn't retain bbs after reload tho. no air leaks, if your adapter leaks, you got a problem. raise your extrusion multiplier by 1-2% or apply more silicone oil/grease. i printed at 101% extrusion, to ensure airtightness. you will need: - a 22-2 foster fitting, you can find em for less than $5 on ebay. - m5x20 screw, to hold the button on. or you can print the provided pin and shove it in there. wont be as secure but itll work. - a small spring for the button. - a 2x15x19mm o ring, if you damage your mag's o ring. that's the size youll need. other than that, you just use the screw and the oring that comes with your mag to attach the adapter onto the mag. if you need help, look up primary airsoft's video on how to do that. I'd recommend using some silicone oil or grease on the o rings and on the screw end of the 22-2 fitting though, just to ensure air seal. credit to itachi for the original file, although redid almost the whole thing. basically only used the top 20%.
