15/50 ml conical tube rack (3x each)

thingiverse

Here is a 15/50 ml conical centrifuge tube rack, from my small range of printable labware. The goal was to make items which: - Are functional (in this case securely holding Falcon tubes upright) - Use minimal plastic, and so are quick/cheap to make - Require little to no supports - Take up as little bench space as possible - Can be easily tweaked and combined to make whatever related custom labware is desired This model is a combination of my [50 ml](https://www.thingiverse.com/thing:3324289) and [15 ml](https://www.thingiverse.com/thing:3324299) tube stands, with some additional divots for holding standard 1.5 ml microcentrifuge tubes. Note that you can't fill the 15/50 ml slots if you have 1.5 ml tubes in there too!
