SIO2SD v1.0 Buttons

This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/6PpuaMembca

Recommended plastic: PLA for strength. (Be careful about the usual warping at the bottom layers.)

The tolerances are very tight and the case is held together (amazingly well) just by friction. It may take a little finesse when placing the SIO2PC PCB inside of the main case. Of course, if your PCB is a little bit different, you may need to make adjustments.

I had a great deal of trouble getting the buttons to print properly on my printer (I'm still new at 3D printing) so I made the buttons off-center so that they could be printed horizontally and without supports. There is a little too much wiggle-room which may allow them to get slightly out of alignment. This is my only real disappointment. There is an opportunity here for someone to enhance the buttons (or add more of a guide into the case top in order to prevent wiggling).

When printing the main case, you'll want to enable your printer's features for creating supports. (It is likely too long for most printers to bridge the SD slot.) When I printed it, the break-away support worked extremely well. For the case top, you shouldn't need supports (and if you do, it may make the top of the case a bit uglier).

The slope around the exterior of the LCD is a little awkward looking (although fully functional) and could use a bit more optimization.

Be careful when closing the case that you don't pinch the SIO cable when it comes out of the female adapter. It is a very tight turn. This is an unfortunate side-effect of how the PCB was designed.
