ONI - 150g Antweight/ Fairyweight hammer saw

This was a fight against a flipper with titanium top armour. ONI can both, do damage and control his opponents quite well.

Weight: ca. 223g 

Size: fits 150x150 square

I printed the chassis and side armour in 95A TPU. The top plates, glider and the shuffler mechanism is printed in plain PLA. The gear should be printed out of something stronger, I used nylon. Same goes for the weapon arm, I had good results with PA-CF. The weapon blade was cut in 3 mm titanium, normal hardened steel is also ok and should fit in the weight limit. Forks are titanium as well, printing them should also work. 

The disk was press fitted on the motor and then secured with epoxy. The rubber bands/ glider are glued on with superglue.
