Here's an example from me :
https://www.modulargrid.net/p/pedalboards/view/899593(sorry must have deleted the old one)
The model feT on the left was my old (and now unnecessary) attempt at adding the pedal, with the 93 x 116 mm dimensions of the Hammond 1590BB. Next to it is a pedal with a 118mm height that's clearly completely different, and next to that is someone else's attempt at a model feT, with 148mm height that's still not as tall as the 118mm of the Sea Machine in the middle.

The Model feT image was a PNG, with a surrounding transparent surface.
See note from further up:
if you upload a PNG there is no auto image processing involved.
So if the autocrop does not work uploaded PNGs that were edited with an external software indeed give the best results.
I have corrected all pictures of your pedals. Everything should fit now.
