/*
TODO this case has many many problems as it currently is. The following
 should be addressed before it is printed again:
  - not enough space for I/O connectors (the plastic handles have
   to go though the IO holes right now and they usually don't fit)
  - risers are made of plastic and really easily break
  - side perforations for ventilation do not print nicely (probably a printer issue)
  - not enough space for sd card
  - no locking lid for case
