Back mount button for rat

This is a back mount "button" for rat jugular surgery. I print this on Replicator 2 with the light blue filament. Using 100% infill, 3 shells and 208C.
If you don't have access to a 3D printer but are interested in trying this, you can purchase it from http://www.kerafast.com/p-1401-button-tether-for-rat-infusions.aspx
