Parametric PCB Rackmount system by M_G

Last crawled date: 3 years ago

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
