Printing

So far PLA is working fine but I'll update if I run into problems.  PETG would be great.

I printed with 6 walls and 15% cubic infill and that seems plenty strong.  

Neither part should require supports.  Orient the drive mount with the rack ears on the build plate.  Orient the backplane mount with the rebate for the fans and backplane facing up.
