Here's my entry for the 2018 Shadertoy contest.  The theme was human. Took about 3 days of re-learning old code and wrapping my head around ray marching and distance fields.  Great fun.  The most programming I've done in a couple of years. #stillgotit

Not so much a political statement as an experiment in how small stuff can be printed using Shapeways.  I had a bust of Donald already from a previous project but I thought it might be fun to print a head for use on toy soldiers.  A content as my local hobby store provided some extra motivation. 
The first thing I had to do was cut the head off the bust and create a new neck in Blender. Then I scaled the head to match a typical 28mm model head.  I sent this off to Shapeways.   What came back was actually slightly too small.  The problem with small parts is that half a mm is a lot on a head that's 4mm wide.
I really need to buy a better micrometer, with a digital read out.  The one I have is a really basic mechanical model.  This is the key tip when working with Shapeways.  Triple check your measurements.  Then measure again. 

I printed the head using the highest quality settings aka "Smoothest Fine Detail Plastic".  Turn around was pretty reasonable at about 6 days.  Now I just have to finish painting this thing by the weekend.
