Roundeez: A Well-Rounded Evolution

By now, many of you have seen the evolution from my 2024 Red Bull cup holder sleeve, to the birthday gag gift from early this year, to most recently the fully-modular, highly refined Holdeez lineup. In conversation recently, someone suggested I think about a round holder for water bottles that's styled like a crate. Sort of a melding between the Bottlez and Cratez parts from the Holdeez family. Got to say, it took me a bit to work through the math and figure out how to effectively map a 2d sketch from a cubical crate onto the side of a cylinder, but after a few attempts, I got it done the other day, fired off some test prints, and here we are! Roundeez comes in 2 heights (Short Round and Tall Round), and accommodates objects up to 110mm in diameter. This includes up through big bottles like the 40oz Owala FreeSip as well as the Yeti 46oz bottle. Remember, this is just the top part. Grab the Bottomz profile from the Holdeez page and print the appropriately sized Bottomz part for your use. As before, samples shown here are printed in Sunlu's Matte PETG.
