45mm wide PCB bracket

This bracket is designed to hold down a 45mm wide PCB, nominally 2mm thick.
There is a little wiggle room, but for this version (solidworks file attached if you want to modify it), I'd recommend board widths of 35-47mm, and thickness 1.75-2.6mm.
The bolt holes provided are 4.5mm diameter, to suit M4 bolts.
