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

thingiverse

Here is a versatile and space-saving 15/50 ml conical centrifuge tube rack from my collection of printable labware. The objective was to design items that meet the following criteria: - Are functional, securely holding Falcon tubes upright - Use minimal plastic, making them quick and inexpensive to produce - Require little or no supports during printing - Take up as little bench space as possible - Can be easily modified and combined to create custom labware for related needs This particular model combines the functionality of my [50 ml](https://www.thingiverse.com/thing:3324289) and [15 ml](https://www.thingiverse.com/thing:3324299) tube stands, with additional divots designed specifically for holding standard 1.5 ml microcentrifuge tubes. Note that you cannot fill the 15/50 ml slots if there are 1.5 ml tubes in place as well!
