UPDATE the original model was the wrong size SD cards did not fit and LID did not fit. SO I scaled it slightly (reprinting now) enhanced the interfaces more and also remade all the slots (holds 21 cards now)

Just cleaned it up more for my personal desires.

Reduced the thickness of the bottom of both parts to remove the need for infill at all. print 3x3x3 and no infill is required. printing a test now at 0.3mm layer height.

Got rid of the holes and the logo as first layer is where prints fail. added the logo name back to the side as an embossment. looks cool and won't mess up the print.

chevroned the corners so ringing won't ruin fit. should let it be printed faster as well.

eliminated the bottom fitment all together. I personally would rather lose that feature and not need support :-) shortened the print time by 2 hours for a slow print. less plastic too.

Cool design. I may remix again for a more complex first layer of the lid to inlay designs in multi color for the single color masochists out their like me :-)
