PCB prices at EasyEDA take a steep rise when one of the dimensions is over 100mm. Smaller knobs were found to replace the 31mm knobs. EZ-Key Bluefruit doesn't seem to be in stock anywhere. For all these reasons the schematic was changed. The Bluefruit was removed but its pins were moved to the spare I/O port so it could be added later. The spare I/O port was changed from an 11x1 header to a 2x6 so it should be more rugged.
The outline was changed for the smaller knobs by moving the encoders closer together. The board also shrunk because the Bluefruit was gone. The spare I/O port was moved inside the Teensy controller footprint to save more space and keep the port holes near one another. This time, traces were laid on both sides of the board since the cost of the boards doesn't increase significantly at this size.
The enclosure was resized with the new dimensions. This was a fairly simple matter since everything was done with parametric modeling. It was as simple as plugging in the new coordinates.
