PCBMaker is an application for PC and android that allows to design small and very space constrained circuits, to be fabricated using a CNC machine.

The program shows an empty grid. Every cell and their sides can be populated with cuts, pockets and holes to compose a PCB. If the size of a single cell is changed, it will affect the rest of cells in the same column/row, so the size of the overall circuit will change, without need to touch the traces.

Circuits created, can be saved, edited and exported to GCode
