@MegaMan2k I'm not sure if this fits your 90 degree joing criteria, but will link a small dab rig i love below.
I have 2 bongs. First was a minirig through TAG. It is nice, but has 15 slits in a showerhead or ufo perc. Works greta, is smooth but i wanted something with less filtration and water. After getting my second, i notice less flavor in this one.
The one i use now all the time is from aqua labs:

it is sold out right now, but was when i first waited for mine. They seem to come in stock pretty regularly.
But it is great, i use maybe a shot glass of distilled water when i fill, so maybe 1 to 2 ounces of water. Has 2 or 3 holes, i think there is a 3rd on the bottom but might be wrong. Very stable/sturdy using a 25 mm banger and axial coil.
I have wanted to buy some high end glass, there is the mobius atom v2 which i really like, but can't bring myself to spend that much on glass when i don't know if i will like it, and the aqua lab one is perfect.
