Rick roll QR code patch
I saw northerncore's rick roll QR code and wanted to make it into a patch.
So i did.
I printed this in TPU so it can be sewn onto clothes or bags but it can be printed in other filaments.
I used Prusa slicer to see what layer i needed to swap the filament on my ender 3 but you can make the layer change automatic on other printers.
Happy rickrollin!
