Top Cover for Lulzbot A0-100 RAMPS 1.4 Cover

This is an attempt at creating a cover that will fit the Lulzbot AO-100 RAMPS 1.4 base. This is also my first STL file, and my 3d skills are a little rusty, so my appologies in advance if anything is off. I haven't tried printing this yet, so if anyone does before I get a chance, please let me know if it works and or what I should do differently next time.
