Monoprice Select Mini extended bed brackets (fixed)

Cleaned up geometry, added spacing for holes at RepRap standard 209mm across.
Added mouse-ears to corners because this should be printed in ABS (or similar) and it wants to warp BADLY.
Having very bad luck printing in ABS and may TRY in PLA hoping that proximity to heated bed won't cause it to bend or warp while in use.
Update: put structure under limit switch bumper so no overhangs exist.
Expanded mouse ears from 10mm to 15mm because one corner still warps when I print these in ABS.
Update: Added modified (and cleaned up) rear rail.
I am going to be printing these today.
Any constructive feedback is appreciated.
Update: ok, so decided to use PLA - these pieces won't be near the hot end and the bed won't get to anything hotter than 110c, so it should be ok.
