QR Code magnet - use for guest wifi access - parametric / openscad

go to https://ridercz.github.io/OpenSCAD-QR/ and enter your QR code text, and it will generate the data for you. copyonly the qr_data array into the scad file.

for guest wifi, useWIFI:T:WPA;S:;P:;;, e.g.WIFI:T:WPA;S:Get off my LAN;P:guest password;;

I would also recommend changing the magnet size variables, and testing it with your magnets before printing. use the magnet_test() module for this.

There is also a module for single extrusion, where you would pause after the base 3mm is printed in white, change filament to black, then resume and print the last couple layers for the black part of the QR code.

I would recommend using the top view in openscad to check that the QR code works before you print it. You may need to turn off the axes. I would also leave the colors as
