Airsoft m4 and ar15 style mag well grip

I used 2 20mm m3 bolts to hold them together. I printed this is pla and it works fine. UPDATE: Unfortunately, I am kinda in a financial problem right now and I had to sell all my guns so there are no longer going to be anymore iterations. Update: V2 Made the grips more ergonomic 5 layers for top, bottom, side 25% infill no support V3: white More ergonomic Changed Logo V4:green Grip will now sit flushed on the side V5:pink The grip now sits more closer to each other V6: Forgot to add. My bad Only minor adjustments so don't worry about it. V7: brown The rear points are now closer Supports are now recommended for the front.
