5 years ago I made my first 3D printer (an Ultimaker) one of my first prints was a bong. I actually ended up using that bong for 2 years before leaks on the bottom made it unusable. Now, I'd like to give back to the community with my own 3D printed bong design.
Many iterations on this design have got me to a bong that's functional and easy to print.
Here are the Specs:
Internal Splash Guard
10 Inches tall
6 Oz for optimal water level
I hope you enjoy :)
I've been printing these bongs in TPU and they work great.
I recommend 5-6 top and bottom layers to prevent leaking.
Besides removing the skirt this print is ready to go after printing. I would recommend running it through the dishwasher or cleaning it yourself to remove any burnt filament left from your nozzle.
Grasshopper in Rhino
I used algorithmic 3D modeling to quickly iterate on the design of this bong. Grasshopper makes it easy to change one dimension, say height, and have the rest of the model adjust accordingly.
