Raspberry Pi 3B and buck converter case

This case fits a Raspberry Pi 3B and an LM2596 buck converter from Ali Express, with mounting holes spaced 58mm and 28mm apart (center to center of screw holes). This is the bigger version of the buck converter with am 7 segment display. I've attached an image of it.
All internal components can be mounted using m3x6 screws, just screw them straight into the plastic standoffs.
The case can be mounted using short countersink wood screws.
The case lid simply snaps into place.
I've also added mounting holes and a cutout for a 40mm fan. Use the original case lid if you don't want to use a fan.

Edit: I've added a model with m3 screw holes for the lid, instead of the snap fit.
