Parametric PCB Rackmount system (Q59655)

This OpenSCAD script will generate a single part rack for mounting multiple double-stacked 25x25mm Radio->USB "base station" PCB units. This allows the units to be easily slid into the enclosure where they will be held securely by friction and locked in place by micro-USB plugs which attach at the side. These racks will be acetone-welded into commercial ABS enclosures for a professional looking, low-cost and secure medium scale technology build. This would be of use to someone who wants a modular system for securing multiple stacked PCBs within a larger enclosure in such a way that they can be readily removed. Changes from previous versions: v0.7 - simple single stack versions for pole attached units - decrease thickness of layer separator or increase width of cutouts on each side by 0.2mm (measured gap after printing probably due to tolerancing etc.) - add cutouts on bottom to help with sanding runners smooth (sized for standard nail file/emory board width of 12mm v0.6 - use rounded cuboid for USB plug cutout to attempt to prevent roof from falling in v0.5 - fixed cutout for USB above thicker shorter section by placing difference operation across entire union operation v0.4 - added support to thicker section to help it print properly at large z values - added cap and cutout for USB above thicker shorter section v0.3 - added support to thin section to help it print properly at large z values v0.2 2011-12-13 - make base thinner - make tray walls taller - remove tray lip - a 4 base station unit with mouse ears in a hollow cuboid tray v0.1 2011-12-13 - first attempt a 2 base station unit with mouse ears in a hollow cuboid tray
