Bộ chuyển đổi Onion AR15 Glock AR9

Don't know exact original designer (Socom458?), but this is a heavily modified version.

I don't have a consistent username, but right now I'm OnionInACage on other sailing sites.
 

Printing features:
- Tolerances are about 0.2mm throughout, so you better tune your printer
 STEP files are given, so hopefully you can manually cut the tolerances further if needed
- All objects in the STEP are oriented with their intended printing face down
- This was designed to print with no supports, with the exception of the lever body
 Steepest angle is around 31 degrees, except for lever body
- There are two thin triangles near the mag-lock designed to be used as print supports
 You can pull them off with pliers or something

Features:
- Fully 3d printed. No screws or springs
- You use 1.75mm filament as the joint inserts
 Cut it by eyeballing it
 If your printer is calibrated (holes are 2mm diameter), friction will hold it in place
 When inserted into the lower, the walls of the lower will naturally hold the filament in place as well
- Glock mag last-round-slide-lock cutout is used to prevent the mag from slipping upwards
- Glock mag is removable through the paddle lever action, or you can drop the entire thing through the AR15 mag release
- The lever insert lock can be used to prevent the lever from disengaging
 There were multiple easier ways of creating this feature, but I wanted it to be flush with the model and also not easily fall out
 You install it by fitting the key hole, pushing half way, and turning clockwise
