Parametric sketch based 3d modeler in your web browser (Open source)

Hello,

I was on github a few weeks ago and discovered a project that has a lot of potential.

It is a 100% javascript based 3d modeler. It uses parametric sketches with constraints. Supports extrudes, subtracts, revolves, ect.

It has a lot of potential. Also it can be self hosted and all the source is there on git hub to get it going.

Made a video for it here.

It can export an stl file for a printer too.
