tube cube

thingiverse

This is a precision-cut block for holding test tubes and centrifuge tubes in various sizes upright. It can accommodate 16mm test tubes or centrifuge tubes (similar to 15ml tubes), 1.5 ml tubes, and tiny .2ml PCR-type tubes.\r\n\r\nThis design is intended specifically for laser cutting and will yield well-cut results from 3mm wood. Since I use K40 Whisperer on a budget-friendly Chinese laser cutter, this basic Inkscape SVG file works seamlessly with that versatile tool (Scorch Works deserves the credit!).\r\n\r\nI created it randomly, but I deliberately made it the size of a standard Rubik's cube for no specific reason.
