I just published my holder design for SKR 1.4 Turbo board for mirrored Bear Upgrade. Although this would work in non-mirrored setup, or any setup that has 2040 aluminium rail and needs to have board with SKR 1.4 dimensions mounted to it.

I've been testing this design my 3D printer running with that board for so long, I forgot I had it in drafts.

My rationale for swapping places the logic board and the power supply, so that X-axis motor doesn't get in a way of logic board and I can have easy access to it, cables hanging out during upgrades and mount extra stuff right next to the board, like the fans.

This is all written in openscad, the source code is here -- https://github.com/avolkov/2040-mount

I also have support for MKS GEN 1.4, which is really dated now, but still works pretty well on my other 3d printer.

If you are looking for a custom solution for your board, you can just tweak bolt pattern placements for one of the existing designs.
