About this 3D model

This is an adaptation of the standard Ultimaker drawings, but with some handy features thrown in. Notes: -All lettering on the parts has been removed for less clutter in the acryllic version -Slider blocks have 1mm more depth to improve tension of the belts -Adjusted the size of the holes in the slider blocks to allow for a smaller kerf in acrylic -A new construction to set the height of the Z-endstop, either mechanically or optical -On/off indication next to the button -Adjusted tabs on the spool holder (but will probably break anyway, just use glue) -Changed the layout of the extruder motor holder so it has more meat near the bowden cable -Removed silly holes in building platform center. please note that UM silently have released an update (V1rev3-3, april2012) whose changes have not yet been plowed into this version. One point to notice though is that UM decided to publish this file under a CC-AT-NC licence, which means you cannot make commercial copies of it. Since I made this derivative, it has to be published under the same licence, which means UM can not use commercially themselves. Please change that.
