Swiss Army Tube Block of Science V.1 (SATBOS)

In biological sciences, we use 6 different sizes of tubes for samples. This two part block, is the only block I know of that can accept all 6 types of tubes. I designed it so that I could split into 2 halves to be used as 2 separate racks. I\'m really excited about scientists and hobbyists being able to produce useful equipment at home... provided they have access to a 3D printer.

Tube sizes that it holds include: 0.2mL, 0.5mL, 1.5/2mL, 5.0mL, 15mL, 50mL
