I am working on a free node based solids modeller perfect for 3d printing, carpentry or hobbyists. Its roughly similar to Rhino/Grasshopper. I call it Nodillo!

Check out this twisty vase demo: https://nodillo3d.com/s/VmP0nJdKRcPazQ1g

You can also share you files and create sharable configurations as well. Here is the same vase as a configurator: https://nodillo3d.com/v/a9REIEZIDYGtzZRA

I would like to do a more detailed intro class to help people learn how to model with nodes.

Hope you enjoy it!
