There’s a really cool and handy QR code to STL model generator out there from printer.tools that lets you generate a QR codes as STL files. The labinator has one such QR code printed up, but since I do not have a dual extusion head printer, I whipped up a quick holder for the QR code so the outer border could be a solid color rather than 50/50 black and white. That’s really all there is to this one - nice and simple.
To construct this model, I just took the generated QR code STL file and imported it into Sketchup. Simply grabbing the outline of the shape and using the offset tool to add .3mm gave the inside proportions. Using the offset tool again to add the border and extruding to the desired height was all that was left to do.
With such a simple model, the original print was the final print - no need for many prototypes. I did end up printing a second holder and QR code, though. To protect the raised edges of the code and give a really nice finished surface, I covered the surface with UV curing resin. After curing the resin under the UV lamp, the result was suboptimal. The curing resin shrank a bit causing the resulting model to curve a bit - and the surface of the resin had slightly visible “flow” lines in it. I’m sure with more tweaking and applying the resin in smaller layers, the result could be as-desired… but a raw 3D print was fine enough for labinator!
