TBS Oblivion Frame 30mm to 20mm Stack Adapter

thingiverse

Designed for Team Blacksheep's (TBS) Oblivion frame, this adapter enables a 20mm stack with M2 screws to be installed inside the canopy without requiring any drilling into the frame. To assemble it, I use M2 Socket head hex screws measuring 25mm in length that are inserted into the bottom of the adapter. A hex spacer is then screwed onto the top of it. The adapter must be properly oriented when bolting through the frame so that the grooves in the adapter align with the frame's design. This ensures the plate remains thick enough to withstand stress on the stack during crashes. I printed mine using Flexible PLA, which has a higher shore rating than standard PLA. You can likely use TPU as well, but make sure your infill is high enough so it won't rip apart or become too squished when bolting to the frame.
