Mini Test Tube Rack Multi-Pack (R2)

thingiverse

This is an updated version of my earlier Economy Style Test Tube Rack, redesigned for use with small 3D printers. I've created a multi-pack of mini-sized test tube racks that can be printed on compact machines. *Warning: I only had time to test print the smallest 1x3 rack so far. To fit it properly, I had to enlarge the holes in the top section. If you encounter any issues, feel free to reach out for assistance. Additionally, I modified my old Solidworks files to ensure they're formatted correctly for 3D printing by placing them on the front plane instead of the top plane. The large test tube rack can be printed on a 6"x6" print area with a Lulzbot mini, but you'll need to access Cura's advanced settings and disable the "skirt" feature to make it work. I may revisit this design in the future and shrink it down further, but for now, I'm focused on other projects due to a current shortage of filament.
