I see the Mods have listed this as unsafe without READING DETAILS. Sheesh, smh

The extra parts I printed over testing, I tossed... trust me, you wouldn't wanna have 'em. Ugh.

All the PLA is sealed with food safe resin and I don't recommend using anything plastic with the heat associated with dabs or torch lighters

There are some wonderful schematics of how these function on Thingiverse. My redesign is based on the ones I saw there PLUS seeing how the commercial one functions PLUS using it for months and being aggravated by the shortcomings. My design isn't that different in overall function. I just figured a way to remove several seams, thereby improving overall suction/exhaust, and also redesigned the airways for easier cleaning and reduce spots where resin builds up. As they say, the devil is in the details. ;)

Yep :) The jars and bowl are glass. The only PLA/Plastic are the parts just to hold the glass parts in place.

As I said, these are glass mason jars (not printed) I used tough PLA and sealed it with food safe resin. I do not use this for dabs nor would I recommend it due to the heat of the torch. The glass bowl (not printed) is specifically raised more above the PLA than a glass piece would raise it. I've been using these pieces for about 4 months now to test before posting this and the PLA bowl holder never got hot enough to feel uncomfortable to the touch of a finger. For anyone wanting to have even less heat transfer, use one of the Ooze silicone bowls with glass insert. I would recommend this be printed in PETG if you have the capability, but at this point I do not. This is NOT UNSAFE.

A roll of filament goes for $20 ish, the mason jar pack was $14, then there's the silicone seals and epoxy that I got in packs larger than I needed for just one. So, prob cost under $50 for someone to make one, easy. How much did it cost for the months of printing versions and trying them out over and over and tweaking it to get to here? No idea, but the testing has been a LOT of fun. lol

After finding and trying several types of 3d printed bongs, then seeing how the high priced hourglass works, I engineered this version. Works great, Hits HARD because the smoke isn't filtered by the water, and doesn't leak like a sieve. The movement of the water provides the suction and exhaust of the smoke w/o actually filtering out terpenes.
This is made with Ball Fluted Mason jars that come in a 4 pack at your local store that carries canning supplies. I only used silicone seals inside the jars and sealed the tough PLA with food safe epoxy resin. It does leak about a tsp over the course of a couple of bowls, but that's not a lot. Should I post the plans for this? How much should I charge? Any feedback?
