Rectangular speaker Grill

I am building a bartop arcade cabinet. inspired by IliketoMakeStuff and i ripped apart an old pair of speakers( http://www.microcenter.com/product/220684/Pro_Sound_2000_Stereo_Speakers ) to create the sound system, the speakers are rectangular and 2" x 3 5/8" a quick search showed i was on my own for speaker covers, so i searched thingiverse. i liked wsy's design and stretched it to make it "rectangular". This is rev one, i am already thinking about screw holes i should add, and I might have some Stl issues, it cleared netfabb, but i think i have some double walls that might make it into the printing process. I'll find out.
