Simple QRCode Generator (openscad)

My previous qrcode maker wasn't necessarily the most straightforward approach to the making of 3d qrcodes as it needed some Python knowledge. Following a few requests from users, I looked for a better alternative and found the scadqr project from "Darwin Schuppan et al." from which I was able to make this easier approach. 

You can either use the Openscad file or the MakerWorld customiser to generate yourself a qrcode from a link in 3 different styles:

• Raised: the inner part is raised above the main plate (2.5D) to allow easy printing in 2 colors without an MMU and a nice visual effect

• Inset: the inner part is lowered inside the main plate. This has fewer small parts and is flatter than the “Raised” variant.

• Flush: Both parts are mixed together in one plane, this requires an MMU system but has the smoothest finish

Printing Information:

• Once generated, split the model to its parts in the slicer and change the color of the backplate. You can also do this with a filament swap for the "Raised" and "Inset" variants if you don't have an MMU printer but the “Flush” variant requires it.

• You can print the model upside down for the “Flush” variant to have a better surface finish

• Use a brim if needed

• While by default a purge tower can be generated, you don't need it for the "Raised" and "Inset" variants, as there is no overlap of colors

Remarks:

• The joined 3mf files are there to give good settings to print your qrcode, you should replace the qrcode model with your own since it makes no sense for you to use the placeholder.

• If you have a qrcode img/file already, you can obtain the link to paste in this generator by scanning it (with any qr code scanner) and copying what is displayed/received.

• The “Flush” variant will look like a regular 3d rectangle, once you separate the model to its parts and change the colors it will look as expected.

Note that the scadqr source-code is under MIT license. As this type of license doesn't exist on these 3d model platforms, I publish this under CC-BY but you can find the relevant license file joined. Note as well that to make the customiser work, the API needed to be copied-in (as disclosed inside the code) and no credit is taken for it by me of course.
