Bong Adapter for Desktop Vacuum

“Multisuck” = tapered inlet to accommodate any reasonable bong with round mouthpiece. A thin rubber lining to the inlet cone might be required. The files for “insert cone” may be needed in order to establish a good seal. There is a cone print for the brave ones, but i recommend printing flat and gluing in place. Use a soft flex material like TPU. You may want a brim on this due to minimal surface area contact (or flip and use supports). 

“Sucky” = fits my bong perfectly, requires some random o-ring I had kicking around. requires support material

The “army of small square desktop vacuums” which this fits includes but I'm sure is not limited to “ODISTAR”, “Vishui”, “IGOKOTI”, “TRZLIFE” (Amazon sellers). I based my design on a photogrammetry scan of my unbranded one (xmas gift several years ago). Printed out the concept and it fits perfect. you can remove or retain the filter, i suggest remove, as it impedes suction significantly.
