Small Space Efficient 15 Ml and 50 Ml Centrifuge Test Tube Rack

Wanted to design and make a simple but compact test tube rack for 15 ml and 50 ml centrifuge tubes. The rack is 3D printed from PLA (or whatever you have loaded onto your 3D printer!), occupies just 3 inches square but can hold 4 of the large 50 ml centrifuge tubes and five of the 15 ml centrifuge tubes and some combinations of 15 and 50 ml tubes.

You need access to a 3D printer or can change the design to a laser cut option. If enough interest I can upload a laser cuttable design too.

Download the stl file and import it into your slicing software, slice it with 10% infill, no supports or adhesion mesh and at medium or low res settings and print it. And you have the nicest little test tube rack.

If you don't have a 3D printer, you could go old school and drill holes in a block of wood cut to hold the tubes.

enough said!
