Description
Slightly modified the spinner ring http://www.thingiverse.com/thing:188275 to show an ECG trace.
I printed the ring in Colorfabb Copper and Brass filament (0.2mm layer).
Better print the new thicker spinner. It's more resistant to polishing
this file is for a US ring size 6.5
This is for medicine addicted! ;-)
