Custom PCR Tube Rack Ends

thingiverse

Update: self-stacking version requires no alignment ring. Customizable PCR tube rack offers flexibility. 1) Print both ends, almost like bookends, for a secure hold. 2) Utilize laser cutting or 3D printing to create custom hole patterns, such as those produced by a Glowforge. 3) Employ the 3D horizontal alignment bars to line up multiple racks in a row. 4) Stack the racks vertically using the vertical alignment rings. 5) Although these parts are press fit, they can be glued into place for added security.
