Raspberry Pi Angle/Upright Mount

I was short on floor space in my current project so I decided to make an angle/upright mount. Has Raspberry Pi B+/2 hole spacing(49mmx58mm), might work on other boards but I'm not sure. Board mounting holes are 2.7mm diameter(works well with #4 sheet metal screws) and 7 mm deep(so don't screws longer than 7mm+board thickness). Bracket mounting holes are 3.9mm diameter(clearance hole for #6 sheet metal screw). There is an inside and outside version, I didn't put a back fillet on the inside version to make printing easier. Let me know if you would like any changes/revisions. Thanks!
