I don't have a 3-D printer, but we have a friend who does. He told me to take a look in the Thingiverse and see if there was anything I could use.
Well...37 pages out of over-130 pages later...I had a whole list of things I "neeeeeded." 😆
Does anyone else use 3-D projects in your aquariums? There were some incredibly creative things there! I'd love to know if you found some cool "thingi" to use in your fishy world.
