🖨 Print Notes:

Recommended material: PETG or Nylon for durability and impact resistance - I printed this in PLA but used 95% infill as i found it to be the best.

Supports required: Yes, depending on orientation

Hardware:  M6 and M4 bolts and M4 nut - Can't be 3d printed have to be metal.

This is prototype version 4 but i have found it to work very well as i have tested it at bike parks and big jumps and am still one the same one with no signs of cracking. - Remember any problems REPORT them!
