This is a project that I have been considering. I have some of these tiny strings of lights that I want to use. Glad to find out that there is work to be done on the file.
Next Thingiverse object you can save yourself a little time of you have CC - in newer versions of Illustrator you can select all and Join (ctrl/cmd + J), save yourself all that lassoing. Will even work with points that are near each other but not exactly overlapping.
That creates one giant path with stray lines between everything. This file has a lot of objects in it, most of which have other objects inside of them. Pretty much a worst case scenario for selection.
I’ve pushed the cutting plugins these guys have. I promise I don’t get anything from them lol.
They also have a concatenate plug-in that is designed to join paths when using multiple selections. It allows you to specify a few variables to help it not go crazy. I haven’t tried the concatenate plugin, but it might be worth checking out the trial.
I look at that tree and wonder if the Glowforge could defects enough to just heat something like acrylic just enough to sag and not cut ir engrave. If each layer were done in acrylic and after just heated differentially with each set of branches on a post 1.5 or 2.0 times the distance between them the slump down and the outcomes could look nj
It is often a problem when bending acrylic to have a sharp enough line to have a sharp bend and not heat just each side of the line. This is particularly true if the line is not a straight one. As the temp needed is ~300F that sort of heat would be at the low end and even a precise zigzag would not be a problem.
