5ml Conical Centrifuge Tube Tray

I designed this to hold the “CentriCutie” 5ml centrifuge tubes. It holds 50 of them. It should be able to fit most 5ml conical tubes, but I posted pictures of the tubes I based he holes off of. 

I have printed this model with both PETG and PLA and both have help up fine over time. I would not suggest putting in the autoclave
