About this 3D model

This is a (fools's? naive?) minimalistic Z extender for your cupcake cnc.Designed to be quick to print/assemble/install without having to dismantle your cupcake.WARNING !!! It dramatically decreases X and Y !Z: Up to 220mmX: Up to 65mm (it could easily go up to 80mm)Y: Up to 60mm (55mm?)Those are sizes for the whole length. At some Z levels X and Y may be bigger.However it uses the whole length of the Z rods (there's a lot of designs that can fit here) and you can switch from this thing to the standard cupcake setup in a couple of minutes.More pictures: http://aubenc.imgur.com/cupcake_cnc_zextender#mdmpi(The example in the picture is a 220mm tall print)"z-ext.zip" contains all the other files available to download.
