I have found a cheap enclosure for my Everdrive TG. I use an enclosure from an old PCMCIA cart. The Everdrive TG does fit in fine. I've just added a small piece of felt to stabilize the cart when being carried.
I actually bought one of these for my Turbo Everdrive, but it doesn't work with BuffaloWing's 3-D printed cover. I ended up using it for my Arcade Card Pro, since I didn't have a case for it. Instead, I converted an old Keith Courage case. The cover of the case bows out a bit, but it does close.
YAGRS, How much bigger is my 3D cover? Can you tell me how big the opening is on the case in metric (mm)? I made a low profile version for myself and I might pick this up if it fit.
I just measured, and it looks like it will fit if it is 5 mm thick or less. My Turbo Everdrive with the cover on it is just under 8 mm. If my Arcade Card Pro were much thicker, it wouldn't fit. Hope that helps!
