Motor Mount Spacer for HK Color 250

The retainerclip of my Multistar Elite 2306-2150kv was rubbing around the centerholes of the motormounts of the HK Color 250, so i made these 2mm thick spacers with a 10mm centerhole and only the 19mm spaced mounting holes since the motors came with only 2 screws each.
