Giá đỡ ống ly tâm 50mL (3x3)

The goal was to make a test tube rack that could print on one print bed (MK3S+) to use for our lab.  The commercially available options are too expensive for what they are.  

This is easy to assemble with just a pair of pliers, pressing the clips into the slots on the side prints.  Take care to align the sides such that the ‘shelf’ in the slot is oriented to the outside of the rack.  The spacing allows for up to nine, 50mL centrifuge tubes to be placed with a little wiggle room.

A .gcode file is available with all parts in PLA, which is the majority of the ones printed for our lab.  

Consult a chemical compatibility chart for the appropriate material for your laboratory use.  Our lab uses PLA and PETG.
