Maybe one of these could be included?
With the Rpi screwed onto the back door of the Picade, it’s necessary to unscrew it to remove the microsd card.
Admittedly this isn’t something I do every day, but I do occasionally like to take a backup image of the card before messing about with settings/upgrading RetroPie etc.
I’ve ordered one of these extenders to allow the Rpi to be left securely screwed to the door while the sd card can be removed/replaced for backup.

Would be a relatively low-cost addition to the kit though?
