Summary

A simple double color print designed to beguile those curious enough to scan the strange, small plastic code. It uses a shorted URL from Bitly to hide the code's true natures upon initially scanning it.

It might also just be easier to use white filament and color the top layers using a black marker. Or you could just print the QR Code out on a piece of paper.

Download includes the SVG.
The model itself is pretty small (normally 35x35mm) and could use some sizing up.

Make your own 3D-printed QRCode:

1. https://www.the-qrcode-generator.com/ (Make sure to click 'URL' on the top)
2. Convert image to SVG [see below]
3. Import SVG to Fusion.
4. Import STL into slicing software (ex: PrusaSlicer - see image) and select color layers.
5. Nice~♪

Quick Photoshop SVG conversion debriefing:
-Remove white background via blend options
Select transparent background with magic wand (contiguous off)
-Right click and select "select inverse".
-Right click and select "Make Work Path", hit okay
-Go to "Layer" tab, New FIll Layer, "Solid Color...", "Okay, choose a color (probably just black), "Okay"
-Go to "File" tab, "Export", "Export As...", click the top-right dropdown (that defaults to PNG) and choose SVG

Hopefully that was kinda helpful
