Custom PCR Tube Rack Ends

thingiverse

Update: self stacking version, you don't need an alignment ring. Customizable PCR tube rack. 1) Print both ends (almost like bookends). 2) Laser cut any hole pattern (I use a Glowforge) OR 3D print an insert (3mm thick) with your own hole size or pattern. 3) Use the 3D horizontal Alignment bars if you want several racks to line up in a row. 4) Use the Vertical alignment rings to stack the racks vertically. 5) Although these parts are press fit, you can glue them in place.
