Hedgehog Blood Tube Rack

Gidget was the inspiration for this line of products.  We were using a piece of the styrofoam tube holder from Antech.  It was getting dingy so when 'making' a new one I got the idea to make a Hedgehog model and 3D print a much better looking blood tube holder.  Adding a little fun to the treatment area is always a good thing!

There are two sizes: 13mm and 16mm. These are the collection tube sizes. Common in veterinary medicine are the 13mm, 5mL tubes. In human medicine the 16mm 8.5mL tubes are prevalent. This size is listed either on the tube label or on the tray of tubes. The big question is why more blood would be needed to run the same test?
