M3 Delta Rostock mini Fisheye Effector Hammock

The original for Delta Kossel is 40 mm long as I have the need expanded to 45mm for Rostock mini. (to design carriage http://www.thingiverse.com/thing:1462452 ).

There's an open file sldprt therefore you adjust if you need different dimensions.

The difference from the original is that this thicker 2mm - because the original is made of aluminum.
