Per request, here are the dimensions for the base of the Workprinter XP. This is drawn as though you were looking down on the workprinter from the top. The base measures 7 13/16″ x 23 13/16″ if my handwriting is unclear.
Additionally, there are three wood screws that hold the prism to the base. I measured these to be approximately 1″ long. Three spacers go between the base and the prism assembly; these spacers are 0.375″ thick (tall) and .605″ in diameter. Two spacers hold the projector above the base. These spacers are simply 1″ PVC couplers – ~1″ in diameter and 1.671″ tall.
