A remix of the neat 1.9" 12mm hex RC rims that use an internal beadlock design to clamp the tire to the rim.
Included are only my favorite bead ring as you can reuse the original ones if need be (go check out the original design, it's great) plus the thicker internal ring.
How I Designed This
Hub Position Adjusted
I adjusted the hub center position to be further inside the well and enlarged it by 2% as my aluminum hexes just didn't fit when printed out of PLA.

Deeper screw holes
The screw holes were extended to accommodate 20mm M2 screws - for strength, plus I had plenty of those.

Wider ring
To make my tires fit better, the internal ring is now 5mm wider and the rim 4mm. That fixes tire retention and makes it 26mm wide at the thinnest part.
