test tube accessories

thingiverse

This project was created to prevent test tubes from rolling around, avoiding the need for an expensive rack with delayed delivery. The holder, or "untitled," is designed for test tubes up to 2cm/20mm diameter; larger tubes can be accommodated by scaling in Blender. Once electronics are available assembled, this will be printed. Update: For a dryer version, match the dimensions and add a 1cm-diameter rod protruding 4cm. Enjoy your print after assembly, trimming stringy bits if desired.
