A 2x2 gridfinity test tube holder for 2x 15 ml conicals and 2x 50 mL tubes. Uses 6mm magnets in the base. Prints as 3 parts so you don't need supports.
Assembly
Print the base, then slide the middle on, then the top has cutouts for the columns to press fit into.
Before you glue anything, make sure the holes line up between the middle and the top pieces… unfortunately it's symmetrical so it's easy to put them on in opposite directions.
Design logic
There's a million test tube holders out there but they all have these minor annoyances. I wanted one that was relatively small, but with enough space between tubes that you could grab one tube without bumping into the others. I wanted to be able to see most of the writing on the tube. I don't like holders where the tube pokes way out, making it top heavy and prone to getting knocked over, or tube holders where the tube doesn't touch the bottom so it's hanging by its cap, which means you can't open and close it one-handed.
So since I'm that weird little Venn diagram overlap between ‘printer enthusiast’, ‘gridfinity fan’, and ‘wet lab scientist’ I decided to put out yet another test tube holder. Enjoy!
