Airsoft MP5 3 lug replacement

Before I had tacticool guns with 3 lug mounts, I tried to make a replacement for someone's airsoft MP5. The original fell off somewhere in the grass because of crap adhesive and/or quality control.

The development of the [3 lug installation knob/tool](https://www.thingiverse.com/thing:1733574) required a better model of a 3 lug.

Took the one I had in hand with some calipers, and some drawings for precision (I think primarily using the first image) found on google, and voila, the byproduct is a superior airsoft accessory that can also be used as an accurate base for firearm accessory modeling efforts as well, though until DMLS gets cheaper, you'll need a lathe and a mill.

Ugly attempt at a 3 lug -> printed out rendering for 3 lug knob -> final production quality airsoft product

3D printing FTW. I included the drawings named '.jp', because if named '.jpg', Thingiverse treats them as jpg images and downsamples them so you can't read the dimensions. If you want the full size
