If you'd like to order one of these printed. They are available through my website: https://bit-district.com/gd-emu-sd-card-tray.html

The GD-EMU is an SD card adapter that replace the ever failing GD-ROM drives in Sega Dreamcast consoles. These are great devices but they leave a very large space open inside the console meaning you can easily, accidentally drop your SD card inside the console and be forced to disassemble it to get the card back. These files are to print a tray or finisher pieces that wall off the insides of the console making it not just more professional looking and visually pleasing but also making it impossible to lose a card inside the console. This also makes it easier to insert and remove cards and there are optional spaces provided for additional card storage; making it more versatile as well.

This SD card Tray comes in two pieces. The base bolts to the console in place of the GD-ROM drive and supports the GD-EMU. The shield is press-fit into the lid to finish enclosing off the area making it impossible to drop your SD card inside through an open lid.

There are three different STL files for the base, one includes a set of 4 slots on the left to allow you to store additional SD cards (the slots are staggered to allow easier gripping), another with 5 SD card slots on the right (these are not staggered).. and the third file with no card slots is simply for people who are not interested in this feature.

If you have an old version 5.0 or older GDMU (without any screw holes) then use the "_for_old_rev_gdemu" files. If you have version 5.1 or newer GDEMU Then use the file without that suffix. I believe fitment should work on all Dreamcasts, however if you use this file I would appreciate a comment confirming fitment.
