I designed this mason jar bong kit from scratch, after checking out all the mason jar bongs and bubblers here on Thingiverse. This bong was designed for an 8 oz. wide mouth mason jar. The short ones. Although I think it will fit on any wide mouth mason jar. But then you will probably need a longer stem.
There are 4 parts in this kit. The mason jar bong, the loading tray, the loading tray stand, and the loading tray lid.
The stand will hold the tray at the right height to load the bowl with minimal spillage. The lid will cover up the tray when you’re all done. It’s not air tight but it’s better than nothing. It keeps the dust out. As an added benefit I can fit a standard size bic lighter in the recess for storage.
I raised the area in the open part of the metal threaded ring. This way if you do get any spillage it will be easy to sweep off.
The hot end stem hole is 12mm’s diameter. It fits an aluminum tube with a rubber grommet from one of my old school bongs, with the aluminum tube and bowl. Not glass. The grommet measures 12mm’s O.D. in the recess or groove of the grommet where it passes through the bulkhead, 15.5mm’s O.D. on the upper flange, and 9mm’s I’D. These rubber measurements are approximate or an average because rubber is flexible.
The hole in the old bong that the grommet came from is 11.8mm’s I.D. The hole in my bong is 12mm’s so the grommet and stem fit just a little bit looser than in the original old school bong. But it still seals, it’s just not as hard to put together. I think that’s a good thing for a 3d printed part.
The aluminum tube or stem measures 9.3mm’s O.D. X 76mm’s long, 88mm’s long including the aluminum bowl. Close to 3 ½” overall.
When the bong is seated on top of an 8 oz wide mouth mason jar, the overall height is almost 6” tall.
I get elephants feet on most of my prints. Knowing this, I designed a little groove into the loading tray stand. It kind of traps the elephant foot of the loading tray, holding it in place. It works for me. YMMV.
It is a compact and efficient bong. Very easy to clean.
Very easy to print too. No supports or brims or overhangs.
Looking at the pictures I don’t own an Ender but I use an Ender build sheet on a delta printer. I know it looks dumb but it works and who is going to see it anyway?
I printed the bong in PLA .2 layer 25% infill
I printed the stand, tray, and cover in PETG .2 layer 25% infill
I don’t know why.
Party on Garth.

My stl files are not rendering properly, so I am adding 4 screen caps from Tinkercad.
