Case for AC-DC 5V precision buck converter AC 220v to 5v DC step down transformer power supply module

Case for "AC-DC 3.3V/5V/12V Precision Buck Converter AC 220v to 5v DC step down Transformer power supply module 1A 12W", something like that was in the name of aliexpress, see on screenshots what exactly power supply I used. Pretty simple case, without showing off, has some minor shortcomings, but for me, it doesn't matter much, but if you have ideas how to improve it or to make your own modification - you can find source files for solidworks here.

Maybe later I'll improve it somehow, but not I have no plans about it, I like it as is.

To lock case, use M3x8mm screws or shorter. I used 10mm, but I have some doubts about it. Also, holes can be a little bit smaller, so I can recommend you to initially heat screw by solder iron and when it will dive a little deeper - screw the rest with a screwdriver. That's the all nuances I had.
