Another celtic-inspired design of the Trinity knot, made into a tealight holder. The base needed some work, which I fixed and showed in the uploaded files. I also changed the dimensions of the cup at the end of the stem to make it deeper. The pictures show the first prototype but the actual STL file has the changes. Note: I haven't built the object with the final changes yet but will do over the next few days. I'd love to see how it worked for you.Knotwork traced in Inkscape removing background, and SVG file extruded in Tinkercad. Tealight holder stem made with PhotoToMesh 5 as a solid object. Final assembly made in Tinkercad. Printed with 20% infill. I'm still experimenting with different parameters.
