I use it every day for washes in 24 well plates! 

A fun adapter making it possible to aspirate a whole row of wells at the same time using P1000 tips.

Based on Bilbos sword, extra points if you print it with glow in the dark filament! 

For printing I split it in half and glued it after (.3mf file). It works as is but it's still a good idea to coat the whole thing after printing with a good clear coat or epoxy, to ensure no leaks and good connection with the tips at the end.
