Iwata HP-B airbrush cup extension

for the Iwata HP-B , A great airbrush but sometimes the paint cup could be bigger, so i designed this, print in TPU this extender cup can slide tightly over the existing cup, giving you a much bigger cup to fill with paint etc, it is completely watertight , there is also a separate cap here,
print in TPU 100% infill, no supports or rafts etc.
