Pen cups, bins, a sticky-note tray, a phone stand and more, all on one 50 mm grid. A small printed dovetail key locks any module to any other. No tools, no glue, no hardware.
CAD renderEvery face of every module has a vertical dovetail groove at each 50 mm grid point. There is no male or female side, so any face can join any other face.
Everything sits on the same 50 mm grid, so grooves line up on their own. Modules leave a 0.5 mm gap between neighbours.
The key slides down into the two facing grooves and stops flush with the module bottoms. The joint resists pulling apart and sliding.
Pull a module straight up to move it. The key stays in its neighbour. Add new modules whenever you like.
