Simple one piece pipette stand designed for printing on larger printers (Creality CR-10 in this case).

This is a lab favourite, due to it's light weight, stability, size options, and bright colour options. I recommend transparent green, it looks great in the lab. Cost of a spool of filament is roughly the price of the least expensive pipette stand out there (that I've found), and you can print multiple copies, over various sizes.
