Squirrelbrain's Pi 3 housing adapted for thread inserts

I have taken a wonderful Raspberry Pi 3 case from Squirrelbrain and adjusted the design for use of ruthex thread insert instead of screwing bolts directly into plastic.

For mounting of Pi plate the M2 thread inserts are used. All the of inserts are M3.

Using M2 and M3 thread insert instead of screwing directly into plastic.
