Raspberry Pi 2 Overclock Case

This is my first CAD design and thingy upload, so critasim is appriciated.

I designed this case because I wanted a case that had the fan mounted inside. I use this case primarily for use as a multimedia machine, but can be used for anything that doesnt require access to the pins inside.

I am looking at redesigning it a bit so that no screws are needed to hold the Pi instide the case and to be three parts not two for easier printing.

STL files are loaded in the orientation I use to print. I also do not use supports on this print.

I have included STEP files so that if you want to make adjustments or change the design you can. I created this in Solidworks 2015.

Please comment with ideas for a better design

I have added a new reversion that I have been working on. The new design has been shortened a bit with a slot added for easily changing sd cards. I also changed the fan cover design to mimic lucymewl design. I feel that this looks better and adds more strength around the mounting holes. I also added 2 additional files that has the Top piece seperated into two parts. This allows you to print it flat making print times better, you just need to glue the fan cover on now using super glue or a slurry mix.
