NOTE: the pins are numbered left-to-right when the STMBL is oriented with the USB port on the top.

NOTE: no motor ground is provided on the pluggable connector, instead a ring terminal must be run separately to a ground lug.

* HV board to heatsink: 2mm thick M3 black nylon washers (6mm OD)
 +
* sheet metal case to heatsink: #4-24x1/4" stainless steel pan head phillips drive "Type AB" sheet metal screws (TODO: determine better fitting screw?)
 +
 +
Standoffs/spacers:
 +
 +
* 1pcs 8mm tall, 7mm OD, 3.6mm ID black nylon unthreaded standoffs (unmodified)
 +
* 2pcs above standoff, modified to have a 2.5mm - 2.63mm tall flange, with the rest of the cylinder cut away to have a 2.6mm deep [https://en.wikipedia.org/wiki/Sagitta_(geometry) sagitta]

=== DIN Clip ===
 +
 +
The bottom of the heatsink has a DIN rail clip. The hole size/type isn't so important, as it will be riveted. Here are compatible ones:
