Selling 2x 50mL tube racks, custom design! Each for $10 OBO. Each one holds 9 standard 50mL conicals in a 3×3 grid. They're super lightweight, have drainage holes on the bottom, and they take up a fraction of the bench space compared to those styrofoam inserts we have lying around. Plus they look way better sitting out on a shelf. These are my original design! I got into making labware because I wanted stuff I could actually customize. These two are printed in terracotta PLA. Just FYI - PLA isn't great with heat, so these aren't for autoclaving or running under hot water. For room-temp bench work and storage though, they're fine! Non-reactive with standard things like ethanol. I'm also interested in taking commissions if you want a different color or quantity, a different tube size, or with custom text printed. I may not be able to make it, but I'm curious if you have ideas for other things to make in the lab. These would also make surprisingly fun gifts for the scientist in your life!
