Enlarged Rostock Idler End V1.1 for 12mm Smooth Rod

WARNING DEPRECIATED: Replaced by http://www.thingiverse.com/thing:143186

- Added Stiffeners to prevent excessive loads when tightrning the pulley (I hesitated with the box but I guess this should be suficient )   - Remouved microswitch holder as the stifener surface should be sufficient   - Turned nuts 30° for better printing
