THIS WILL BREAK IF PRINTED IN PLA, PETG, ABS OR PA!

Reccomended filament: BIQU PLA-HR, DUDV2 PLA-B Splat or Sting 3D's FPLA+.

Tested:

Extrudr Hard TPU (58D) - good durability about 40% bounce

Overture Super PLA+ - 100% bounce but broke easily

Overture easy nylon (PA6) - broke almost instantly (the community have suggested “annealing” the print in water to increase durability)

BASF Forward AM Ultrafuse TPU 64D - good durability and 60% bounce (BEST SO FAR)
