YAC – yet another coaster. I designed this one in the process of learning how to use FreeCAD, but I find that manipulating text shapes in FreeCAD is very cumbersome. So, the FCStd file is the base model without the embossed text and non-colorized. The colorization and text were added directly in Bambu Studio, so they appear in the 3mf file.

I'm not 100% happy with the top surface. The included 3mf specifies a top layer using Hilbert curve and then concentric ironing. Pretty good but I don't think it's quite right.
