- 3d printed out of TPU. Designed for the Hobbywing Nano and Red Panda Frame. Will likely work with other 20×20 boards but has not been tested for compatibility. I saved around 10-15g compared to a full size stack.
- Flat on the bottom (nuts or press-nuts are recommended like on the Red Panda)
- 30.5×30.5 holes are sizes for m3 screws
- 20×20 holes are sized for m2 screws
- m2 bosses are 2mm tall
