Description
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

Instructions
Note: you will need to download the rounded_cuboid_2_2.scad and mouse_ears_test.scad files to the same directory in order for the rack files to compile properly.
0. Measure your PCBs and edit parametric variables (padding, unit_separation, max_units, unit_height, wall_t, base_b, base_h) accordingly
1. Generate .STL and print
2. Remove mouse ears (if desired) and sand/file edges of rails until PCBs and USB cables fit with desired level of friction hold
3. Use Superglue/Acetone to attach to inside of commercial project box/enclosure
4. Slide PCBs into rails and secure with USB connector at side
5. Seal up box so it looks all nice and professional!
