Veterinary Lab sample caddy (catalyst)

**UPDATE 5/28/2026 - Version 2 now available! Features an upper section for larger tubes and a open space for pens or pipettes! Also, fixed the page to include a 3mf profile for the original caddy,

I created this model specifically for use in a veterinary lab setting to place whole blood seperators, serum sample cups, and micro-volume tubes without leaving a big footprint. Its small and simple (which the lab techs requested)! 

I do not recommend scaling this uniformly as it may change the sample cup size that is customized for these specific cups/tubes. But you can play around if you need to adjust things based on your own lab materials. 

The caddy in the picture was printed with PETG black filament (shinier than I wanted, PLA would likely print nicer). I used 0.16mm settings to give it a cleaner look but the surface could use some fine tuning or ironing. 

I also added stick-on small rubber feet to prevent the caddy from sliding around. Any basic stick-on feet from Amazon should work. 

Please share your final copy! And if you love it,  give it a boost! :)
