update 12. oct 2014: added 3-5mm version with space when power board is used and mounted with screws

There are two versions:
1-3mm -> Total height ist 3mm, height of bar is 1mm
3-5mm-> Total height ist 5mm, height of bar is 3mm
3-5mm-v2 -> same as above but with a little wider strap space, for people who used screws to mount a power distribution board.

I would recommend to print the 3-5mm version, it is more stable than the thinner version. But test it for yourself ;)
