That's a great idea; I think we should add more presets.
The best add-on to build math nodes! I had to do some custom 3D math computations with Octonions and Quaternions which deal with a lot of math calculations. This add-on did it with no problems!
Cool but generates errors on some Attractors like the Sprott-Linz... ones This is most likely due to the code needing to be updated.
Thanks for the feedback, will have a look into it.
Great for making sure svg files are exported correctly. Note: to add your own presets just edit the preset.py file in the extensions/blender_org/printing_helper/preset.py (at-least for linux). You have to restart Blender for changes to take affect. Tested in Blender 5.0 beta
