Summary

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.

Print Settings

Supports:

Yes


Notes:

Supports are necessary when printing the shield, they are not necessary for the base. You can get away with low- infill (I used 20%) since the part doesn't need to really 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 in addition to 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 dreamcastand 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.

Hi, Can this model be addapted for GD ROM USB V5 (internal)? http://3do-renovation.ru/USB-GDROM_Controller.htm

Because I want to have a better airflow and without the original GDROM the air didn´t come as expect in the power supply. Some people use cardboards parts to take the air to the power suplly but I think will but much better to have a 3d printed piece.

Maybe print just the lower part?

I've recently purchased a USB GDROM and designed a similar tray for it: https://www.thingiverse.com/thing:2379444

Do you think this tray will improve air circulation? Because I saw on assember forum (now offline - maybe never will return...) some people adding a "carton walls" to bring air to power supply circuit. When you take off the original GD rom drive the air path change and power supply heats a lot more.

It's not designed to provide an air-tight path to the PSU but it should provide similar air circulation to how it was when the original GD-ROM was installed. the tray occupies a similar amount of space. Actually probably a bit better than the original GD-ROM since it will prevent air from escaping out the top and through the center.

Nice! Thank you!

I can tell you from looking at it that printing the lower piece wont even come close to fitting. the lower piece is designed to go UNDER the GDEMU, which is a much smaller PCB than the USB-GDROM.

I could design a 3D Printed air duct or a 3D printed tray for the USB-GDROM but I would need to have one in order to take measurements and make test fitments.

yes I would also like to see this for the usb-gdrom... I printed this and it looks awesome thank you for making this product the usb gdrom might be a more popular product since its easier to get the usb-gdrom only goes on sale once in a blue moon at random times.

looks awesome can't thank you enough for your hard work.

Well, if you guys want to chip in and buy me one I'll gladly design a tray piece for it.

do a go fund me and post the ling on forums and on here and see what happens

For those of you with old (version 5.0 or older) GDEMUs without screw holes, I've added some modified files to better accommodate them.

thanks for the great pictures, glad it printed without any issues :)

Great idea for a great machine.

I shall be printing one of these when I place my order for gdmu.
