The unnecessary big QR Code (The easy way)

Hi there,
here is another way (the easy way) of creating QR codes, small or big. I tried to make one as big as I can wit my (Prusa) Mini, just to show off. Jokes aside, I think this could be something for fairs and exhibitions or companies. Or maybe you could make a lamp out of it?

If you like this one, also check out my QR Code business card, but this one is even easier to make.

Design:

1. Got to https://www.qrcode-monkey.com/de and design your QR Code, for a Hompage, businesscard, contact - you name it. They offer the biggest range of customizable designs for your code, that I've found so far. This makes your code a little bit more special and apealing, I think. You can even add a Logo, like I did with the Thingiverse Logo. The desgin process itself is self explanatory. You only need to click the "create QR Code" button on every change you make. Lastly download the QR Code .PNG (default 1000 x 1000 px is fine)
2. Use Lithophanemaker to create .STL file
   Go to https://3dp.rocks/lithophane/ and drag you image on the canvas. Go to "modelsettings" and use the parametrs you like. See the image for the parameters I've used. I recommend to set the thinnes layer at least to 0.6 mm when printing with 0.2 mm ans 0.1 mm Layers. This way the model is thin an flexible, but riged enough to stand upright. Download the .STL. That's it.

Sclice and print
I am using Prus Sclic3r 2.2.0. Sclice it the way you like, I've used 0.2 mm layers, but don' forget to add a colorchange.
How to colorchange

Additional Note:

Can you see the black spot in the left upper corner? I don't know why, but this happens after colorchange, the extruder moves to tht point and slightly touches the white base with the newly loaded black filament, for whatever reason. Maybe calibration? Does anybody know why? I had that effect on several occassions, when changing color.

Have fun and please post your makes or remixes and leave some feedback in the comments.
