Cryovial Colour Caps

Here is a cheap alternative to the Nunc Cryo Color Coders/cryovial color caps for organising cryovials. I have printed this using a 0.8 nozzle and PLA but would recommend a thermotolerant material for long term storage and a smaller nozzle for better tolerances (0.4 nozzle would be perfect from testing). The flanged cap fits cryolabels like the SnapPEEL cryostuck label shown in the image.
