I fully utilized the size of my H2D bed and made this big fella 280% of the original size. I made it 8 walls and this thing is STURDY. The throwing arm I made out of PETG so it had a better chance of not destroying itself (it's more bendy). I also made the W piece out of TPU thinking that would help keep it from destroying itself, nope. DON'T USE THE TPU FOR THAT because it alters the geometry of the throwing angle making it throw more straight line. We don't want straight line laser throws though, (shakes fist in the air) WE WANT TO RAIN FIRE ONTO OUR FOES! (back to reality) HOWEVER! It threw an old dog chewed tennis ball approximately 50 feet like a baseball pitcher throwing a fastball, straight like a laser. Once I put the W piece made of PLA back in there so this thing lobs, it will probably throw it into my neighbors yard the long distance way from my house haha. It stands just over 17" from the base to the top of the throwing arm when vertical. Small guy in the front is at 100%.
