Juul Bong
thingiverse
This is a bong that is specifically designed to be used with the Juul. Simply fill with water right above the percolator and insert your Juul. I printed mine at 100% infill and 0.25mm layer height but i'm sure you can tweak those to your liking. However, don't change the scale/size of the model because it will not allow for the Juul to fit anymore.
