70 mm 90 degree bracket

I needed a right angle mount for a 70mm x 70mm cooling fan. And I didn't see any on Thingiverse so then decided this would be an easy thing to design. I used 123D Design and Meshmixer on my M3D it takes about 2 hours and 20 minutes on medium fill and medium quality with a raft. This is my first official design so let me know what you think and of course post makes!!! :) Thanks!
