http://goo.gl/6oGW9U This is a set of tool holder blocks. Yes, it's that easy as you think! Why not design / print / assemble / organize these parts in our own way? Or, redesign our own holder bricks and join the tab / slot part, just like a interlocking puzzle! The last thing to do is screwing this set on the wall. No more giant printing piece - with unsatisfied design! ========== about the bricks : ========== No. 00, 01, 02 is for screwing the tool holder to the wall. No. 03, 04, 08 screw drivers (diameter 4 / 8 / 9.5 mm). No. 05 quick wrench. No. 06 digital caliper. No. 07 scissors. No. 09 nail drawer. No. 10 cutter. No. 11 pliers. No. 12 smooth file.
