zmr250 arm cover

Thin cover for the ZMR250's arm.  Only two layers, 0.5mm high, almost weightless.  Quick and easy to print.

Successfully printed in ABS and PLA, without supports and without brim.  0.3mm first layer and 0.2mm second layer

You may upscale Z to 4-5mm and print the whole arm, but don't do this.  Use carbon fiber arms :)

Please, share if you print it.
