Getting the mounting hardware ready. Some spare 12mm plywood and a spare wooden dowel were used to create a mount for the PCB to position it behind the mask to be suspended from the dowel.
The plywood also has countersunk screw holes to allow fixing to a wall stud.
For this particular set of masks, I needed to populate all four strings LED pairs. Other masks or applications may need fewer LEDs populated, and may need current limiting resistors depending on LED colours, supply voltage, number of strings, and whether or not LEDs are used in series strings or not.
The OSHW logo is parametric, allowing a the size and solidity vs outline format to be defined at creation.
Similarly, the two pairs of unadorned mounting holes at the top and bottom edges are a four hole parametric footprint use to create hole spacings compatible with LEGO mounting holes in case the board is to be connected to some LEGO at some point.
