SD Card Locker

This is my very first attempt at a 3D model. I couldn't find a locker that would hold my SD cards the way I wanted so I made this. It should print on a small printer like the M3D which is the one I have. I haven't printed it yet, but I believe that it should be printed at a minimum of medium quality and medium fill. I don't know if printing in PLA or ABS will affect the print. The tolerances on the lid are very tight so minimal trimming may be necessary for the posts to fit into the sockets
