Iwata revolution cutaway handle

thingiverse

Unscrewing the handle after every single use was driving me nuts so I created this so that you can remove the needle without removing the handle. I think the idea is pretty much stolen from either Badger or Paasche. The handle has holes to expose the nut and is open at the back so the needle can slide out. There is also a knob to glue onto the end of the needle. Tip: print with a brim, standing up, with the threads at the bottom. Counter-intuitive I know but having a little flash on the threaded end helps by making the fit snug just before you hit bottom when screwing it on. Helps to avoid over-tightening and breaking the threaded part off.
