About this 3D model

This was a sculpture I sketched in 3d coat years ago but found it to be a fun test object to throw at my printers. I've tested it at 0.2 and 0.4mm nozzle sizes and at various layer resolutions (0.05,0.08,0.1,0.12,0.2). It's become the usual model I like to experiment over the years but i'm posting it now for others to play with as well.
