How do you overcome the limited access to the SD card on Raspberry Pi case that is physically mounted to a surface?

Lately, I've deployed a number of Raspberry Pi in the company network. They are ideal for network UPS monitoring [NUT] servers and ad block pi-hole servers.
A power failure last Friday corrupted a memory card in one of the Pi's. Restoring the OS image got the Pi working. The pi are mounted to a wall using the mounting holes (Ellipse 1). In order to get at the memory card (Ellipse 2) I have had to unmount the case from the wall. My fingers are just not small enough and I haven't discovered a tool that can grip the card in such a small space with the case mounted to a surface.
The picture is of a new case I am trying. It suffers from the same problem as others. On a different case I've taken to cutting the plastic around the SD card to enlarge the hole. It looks like crap but works. Recently I've taken to extending a handle on the SD card with cellophane tape (Ellipse 3). Removing the SD card without having to unmount the case is possible by pulling on the tape handle. Getting the SD card back into the unit is a bit of a challenge.
I've struggled with SD card insertion on a Pi3B+ case I had mounted to my workspace. It took a pair of needle nose players and some wrist flexing to extract cards.
Please share your insight if you think it can help solve the case.
