Case for my ZX PicoMD SInclair ZX Spectrum Microdrive Hardware Emulator

Note there are two versions of the top:

• ZXPicoMD_top.stl is for an OLED size of 27.5mm x 27.5mm.
• ZXPicoMD_top_26x26.stl is for an OLED size of 26mm x 26mm which also has a slightly smaller window
• ZXPicoMD_top_largeoled_simple.stl is for the larger 1.54" OLED

I've seen a few other OLED sizes but it is impossible to cater for all. There is a bit of tolerance on the holder so you can go up to 28mm x 28mm for the 1st and 26.5mm x 26.5mm on the 2nd.

Screw size to secure the PCB to the bottom is a self-tapping #4 1/4" long, which is ~2.9mm diameter and ~6.5mm long so in metric a M2.5 or M3 6.5mm should be fine.

For securing the top case to the bottom the screw needs to be 1/2" (13.5mm) long

I recommend adding some rubber feet to the case. If you can get hold of them the original feet are fine, however, I recommend the smaller 3M Black Bumpons (SJ5076) which lift the case to correct height (by ~2.8mm). This height adjustment is a requirement if you plan to connect this to a real Microdrive using the connector block. Without the feet the edge connector will be at the wrong height and won't fit together very well. If you don't plan on using this with a real Microdrive the feet are not needed although I still recommend them for anti-slip.
