A bracket to mount a Teensy 3.2 to a panel, allowing access to the USB connector and both sides of the Teensy board.

This was designed for a Teensy that is 35.55 x 17.7 x 1.52 mm.

You almost certainly want to wire up the Teensy before mounting it, so as not to melt the PLA.

Slope of overhangs are less than 45 degrees, so can be printed without support. The holes may be a little rough at the bridge though, and need cleaning out with a suitable drill bit.
Thinner, wider layers may work best.
