Suggestion: Add board mount functionality

[kalj]

This is a new feature I have been using extensively for more than a year which is the option to add a mount for a PCB / proto board perpendicular to the panel:

Here is how it is used in the panel file:

boardmount_board = [ 80.01, // length
                     49.53, // width
                     [[3.81, 3.81], 
                      [3.81, -3.81], 
                      [-3.81, 3.81], 
                      [-3.81, -3.81],
                      ],
                     2.5, // hole_diam
                     19, // vertical offset (centered if left out)
                     ];

// for adding stability, not completely necessary
boardmount_wedges =
    [[0, // vertical offset from board mount lower edge
      10 // size of wedge
     ],
     [33,10],
     [75,10],
     ];

Currently, the "wedges" need to be manually positioned to avoid colliding with components on the panel.

Feedback on this feature is welcome!

That test print is looking good! I initially wanted to add in something like this, and I ran into some adhesion issues so I decided to hold off on it. But if this doesn't affect the other features, I think we can add this in. Just some feedback:

1. The screw hole definition can be simplified to something like [[5, 5, BOARDMOUNT_HOLE_ALL_CORNERS]]. This is how it's done in YAPPgenerator, https://mrwheel-docs.gitbook.io/yappgenerator_en/standoffs.
2. If we want to add screw holes manually, those can be defined without the 3rd parameter. ie. [[5, 5], [5, board_height-5] ... ]
3. Add to examples and/or docs.

Thanks, @kalj.

Ah, that would be neat for simplifying the screw hole positions. After all, they pretty much always have such a symmetry. I will look into it.

I am thinking about ditching the hole "wedges" thing. I don't think it adds much in terms of stability.

Screw hole positions

@kalj Yup! And I find it easier to measure around the edges of the perfboard/pcb with a caliper. One thing I think we can also define is an offset from the panel, to make sure that the board clears any panel-mounted components, while still keeping the coordinate system based on the mounted board.

Let me know what you think

Wedges

I am thinking about ditching the hole "wedges" thing. I don't think it adds much in terms of stability.

I can't really comment on it right now without trying it out. I say keep it in as an option, but we don't have to highlight it too much for now. I'll check it out when I finally find the time to do some tinkering with my printer.
