Sega Dreamcast GD-EMU SD Card Tray

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 replacing the ever-failing GD-ROM drives in Sega Dreamcast consoles. These devices are great but leave a large space open inside the console, allowing you to easily drop your SD card inside and be forced to disassemble it to retrieve the card. These files print a tray or finisher pieces that wall off the console's insides, making it not just more visually pleasing but also impossible to lose a card inside. This makes it easier to insert and remove cards, with optional spaces provided for additional card storage, making it more versatile as well. The 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, while the shield is press-fit into the lid to finish enclosing off the area, preventing you from dropping 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 store additional SD cards (the slots are staggered for easier gripping), another with 5 SD card slots on the right (these are not staggered), and the third file without any card slots is for people who don't want this feature. If you have an old version 5.0 or older GDMU (without screw holes) then use the "_for_old_rev_gdemu" files, while 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. Print Settings: Supports: Yes Notes: Supports are necessary when printing the shield, but not for the base. You can get away with low-infill (I used 20%) since the part doesn't need to support much weight. The walls are all 2mm thick, so keep that in mind when deciding the number of perimeters based on your nozzle size. Post-Printing: Parts Required: Installation is very simple and requires a Philips screwdriver as well as the 3 screws that originally held down your GD-ROM drive plus the long screw included with the GD-EMU. Step 1: With the Dreamcast opened and the GD-ROM removed, place the base part as shown and bolt it down using one of the original GD-ROM screws. This should be snug but not too tight. Step 2: Remove the stand-offs from the GD-EMU then plug it into the Dreamcast. Use screws from the original GD-ROM drive in the two upper holes to affix the GD-EMU to the base part. Then use the long screw included with the GD-EMU (without the spacer) in the lower left screw hole. Again, these should be snug but not too tight. Step 3: Insert the shield part into the upper Dreamcast case, aligning the circular nub with the matching indent on the sheld. This should fit tightly such that the sheld will stay in place. Step 4: Open the lid on the dreamcast and lower the upper case half directly down onto the lower half making sure everything lines up. Once back together you can re-install the bolts that hold the Dreamcast case together.
