Customisable Adapter Mount

Want to mount a PCB but the holes don't match the plate you want to mount it on? This design generates a plate with captured nuts to act as an adapter.
You specify the X, Y values for the holes in the plate and the PCB and can have as many as you need for both the plate and the PCB.
You specify if the hole is straight through (a common hole for both plate and PCB) or if there should be a captured nut on the top or bottom of the hole.
You can specify how many of the nearest holes to each hole will be joined by a bar (the more bars the stronger, but the more material and time it takes).
You can specify the standoff the PCB will have above the plate.
You can specify the bar width.
Mounting a PCB to a plate is just an example. Anything that needs to be bolted and the holes don't match might find this useful.
