Stackable Shelf Risers & Caps 220 x 125 x 15

This project adds an additional shorter riser & block off cap to the stack-able shelf project by iT Station. This allows for more combinations of heights, either 175mm or 125mm (from base to top of wood insert shelf). Thus in addition to the original riser, adds a 220w x 125h x 15mm thick (for a ~150mm shelf gap). Then added the previously separate riser connectors, along with some cut in half as visual caps to the top-most rise. Same screw holes as before, which were recommended 3.5x16mm to 20mm.
