Ball chamber bong

Printed in 0.2mm layer height and printed water tight for me but your printer settings may need to be tweeked. I also didn't model the hose hole to make the print a bit easier (I just drilled out a pilot hole with a standard drill bit and then used a step drill bit to widen the hole to a standard garden hose O.D (14mm).
No supports needed
6 walls/perimeters for strength and water tight seal.
