/*
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
