This thing is a jig and stand for the LED kits available from Aliexpress (http://www.aliexpress.com/item/Free-Shipping-3D-Light-Squared-8x8x8-LED-Cube-White-LED-Blue-Ray-Kit-Christmas-Gift-3D/32311673719.html).The jig is used to line up the LED faces so that you end up with a square cube at the end of the build.The stand is eh...a stand.AssemblyPrint in ABS and acetone weld the parts together, or use PLA and SuperGlue (which is what I used on this build).Because of the board layout on the supplied kit, I didn't mount the power input socket on the board, instead gluing it to a more convenient place on the rear stand leg, and running leads from the socket to the PCB.In the pictures you can see that after mounting the board, I pushed stiff conductive wire through the holes into the anode receptacles on the PCB - in retrospect, if I assembled this kit again, I wouldn't bother with the receptacles, I would just push the LED anode legs straight into the PCD and solder them in place.I also found it useful to glue the switch cover in place on the PCB mounted switch before mounting the board.
