RC Plane landing gear offset/extension (for skis/floats)

These offsets / extensions are designed for use with the skis http://www.thingiverse.com/thing:1223555, but can be used with wheels and floats as well.
They attach by sliding over the existing wheel mount, then using a 1.5mm screw (servo mount screw) to lock in place, a 3mm bolt is then used to mount the ski / wheel / float. These extensions make swapping between skis and wheels quick and easy, 1 screw to take them on and off, I leave them permanently mounted to the skis.
There are holes integ
