I've remixed this tray so it fits in the back of your Macintosh SE/30 if that's unused. This way you can access the SD card easily without having to open the case.

The fit is very snug, and you can screw the board in place with a single screw like the original. Use two similar screws to fix it to the tray bracket.

I've printed mine in some “beautiful” no-name orange PETG on my Bambu X1C with the following settings:

• 0.20mm layer height
• 15% gyroid infill
• 3 wall loops
• 5 bottom and top layers

Original design by Alan Williams.
