UPDATE 2: I've been tinkering with the design and the new versions, "HkhMp Basic v3" and "HkhMp COMPLETE Basic" are the latest and greatest versions. Enjoy!
UPDATED: the new files fit the hose way better. Also, I split the mouthpiece into two parts so you can print the "mouth" at a higher infill if interested. to print in one piece, just place the mouth file on top of the base file (without scaling, it is 58mm high).
Multiple versions of a hookah mouthpiece for screw-end hose. Most of the basic design work was done in Fusion360 (still learning, and this seemed like a good project to try out), while a lot of the more artistic modifications made in Tinkercad. The threading is ISO metric, which should work for most large ice-style hookah hoses. The first picture is the "2knob" file printed in Carolina Blue, the second is the "Weave" printed in transparent (both are PLA).
Let me know in the comments if you have a particular design you'd like me to add; I'm always looking for feedback and new ideas. Enjoy!
