the aug part is 100% fitting.. the m4 part however... it requires positional movement to engage the bb release tooth inside the mag.. had one 3d printed and it did not work with 4 different types of stanag/nato style magazines. I was super hyped but now disappointed :\ nice work tho as the aug part was a phenomenal snug fit.

What size are the marks made in? mm, cm, inch? And what would be the best mat to make it from?
I have way to many options if i want to print this :p


Thank you, just what I needed. I'll post the make when I finish one.

Hi would you consider making a different adpator? Like hk 417 to M4, i have not seen any around. And 417 mag is very bad.,.,.,,

Hello this adapter is nice but i ran in a small problem it is about 2-3 mm too short for my oldschool marui AEG

What would be the best material to make this out of?

Just a suggestion, but the rear of the adaptor could benefit from a guard for the AUG's mag release catch, as seen on the real steel 9mm mag adaptor:



Hey I was looking for an adapter on the market and this popped up. I don't have a 3D printer but this looks pretty cool and I was wondering if you could make me one? Thanks! Either way, this thing is pretty cool.

Hello, it would be possible to have the battery cap? I lost my during a game.

What material have you found that is strong enough but also cost effective? Would PLA++ be good enough or do you recommend something else?

Are the measurements in mm or inches? Would a resolution of 200 Microns be good?

They are in mm. If your layer bounding is good enough, .2 should be a good resolution :) The m4 part need to be quite strong, since there is a weekpoint in the lip that enters the m4 magazine.

for my M4 mag its to short :( so its dasent work

but great jobs

What part of it is soo short? By how much? I can mod this in Tinkercad. I'm using a Steyr AUG as well.

Looks awesome would you be able to make a G36c to m4 adapter? i am aware they are already ones for sale online but they always seem to break.

I have thought about buying a G36 for another complete mod build. But if I choose to do this, it might be a while before anything comes out from me to a G36 :-( Designing more complex adapters and parts takes its time.

Nice! good photography too
