This is a small rack for cooling 4 culture tubes at 20 degree inclination. It supports standing at 90 degrees for filling, and also setting at 5 degrees for very shallow slants. The design is largely based on commercial products for the same purpose.

After printing, I annealed it while stuck to the build plate. This allowed for successful autoclaving at 15 psi for 30 minutes. Your result may vary.
