Grab the size of MicroRAX beams you want. I used 160mm beams for the long axis, 100mm for the width, and 40mm for the height. You can buy beam pre-cut on the MicroRAX site.

Use the corner connectors to connect one of each size of beam. You can buy these at Sparkfun or the Microrax site.

Cut out some panels for this sides. I laser-cut mine out of scrap wood but this isn't absolutely necessary; you could cut them with a regular saw just fine. Make the panels the same size as the beams but add 4-6mm to the length and width of the panel if you're using 2.5mm or thinner stock and 2-3mm if you're using 5mm stock, the maximum thickness.

Slide in bottom panel to the beams you've just assembled. If they're a bit loose and rattly, stick a piece of rubber band in there to pad it.

Complete the base, adding additional beams and the rest of the vertical struts.
