Test tube rack, multi-use, no supports

thingiverse

Here's a quick multi-use tube rack that prints very easily with no supports and no assembly. I needed a rack model that prints quickly, uses minimal plastic, could be used for different sizes of test tubes, and requires no assembly after printing. This is the result. If anyone is interested in a variant, send a message and I can probably crank it out and post it. If you're going to print a bunch or use them for a commercial or school lab, I ask that you consider buying me a cup of coffee, as I probably burned one cup designing this just for you. ;)
