<p>I know nothing about 3D printing and I was wondering if it is a good candidate for what I want to make.</p>

<p>I want to make a custom game cartridge which looks like this:

<p>Basically it's like a SD card in a custom shell. Now I can produce the inside as a thin PCB (0.6mm-1mm). But I was wondering what the best (and cheapest) way to prototype (and maybe make a small run production) the outer shell would be. The entire cart is about 2mm thick, so each half of the shell would be at most ~0.6mm thick.</p>

<p>Is this something I can do with a typical 3D printer? How would I "attach" the two halves together?</p>

I attach the bottom of the PCB to the print with a drop of a quick setting superglue so that it won't have a chance of getting loose and crashing into the nozzle as the next layer is printed.
