Rework of a Laurel Wreath by https://www.thingiverse.com/yk9219k
The original SVG contains several technical artefacts that make it dificult to create a proper solid in 3D:
- the elements are not merged. They are overlapping outlines.
- the outlines are technically not closed. the two endpoints coincide only when allowing some rounding.
- many of the leaves are disconnected.
- there are many T-intersections, where one arm has duplicate lines.
I've merged the elements, by
- closing all outlines
- making them overlap properly, not just touching with a T-intersection
- extended several twigs to really connect the leaves.
- removed all holes (by makeing leaves smaller
- separated the stems and center part of the ribbon as an extra layer.
The result is Laurel_Wreath_merged.svg
The file Laura_Wreath.FCstd is a 3D-extrusion with 10° draft added -- useful for metal casting. It is still a delicate and fragile object!
The method of applying a draft is a horrible hack. 9 extrusion copies, where only one is an exact perpendicular extrusions, the other 8 are slighly off to the sides, all combinations of (-1, 0, 1) in both X and Y. This wirks astonishingly well, even for complex objects.
The only visible artefact is that very sharp points separate into three, further down.
A much nicer result should be possible with a Minkowski operator applying a cone, stay tuned...
