Hi! This was my first time 3d printing so IDK if I did something wrong. There were strings of residue stuck in some of the holes after the printing. Also, I can't find out how to use it even with watching the video. I use a gravel vaccuum that has an input to take in water, and one tube for it to go out. Do I need a two-tubed-and-one-dirty-water-intake?
Thanks!

was this printed with the holes vertical or horizontal?

Exactly as previewed on thingiverse rendering (not like in photo)

Great idea! Printing one now :)

Thank you! Don't forget to publish your make :)

Great design! I've got a huge aquarium to empty & I need this. I can still see my husbands face when he accidentally got aquarium water in his mouth trying to syphon it. Thanks for designing this!

A friend of a friend couldn't eat solid food for the better part of a decade due to 'tropical fish parasites' ingested while siphoning his fish tank. I'm printing this as much out of paranoia as need.

That's scary!

Thank you! Keep me posted on your husband's feedbacks!

This thing is SO handy in the lab to drain cooling baths and the like without touching the liquid or needing to remove complex assemblies that are sitting in the fluid. Thank you very much for the design! More lab tools please :)

Thank you. It's nice to get some feedbacks from users! I think I will publish more things like this :)
