Recently I have found Shapespark and I’m very excited to use it in the school but I couldn’t find Educational license and also I can’t find Rhino plugin also 
We don’t have an exporter plug-in for Rhino, so to transfer your Rhino model to Shapespark you’d need to export the model to an intermediate 3D format like glTF, FBX, COLLADA (DAE), and then import the intermediate 3D file to Shapespark.
I am sorry, we don’t offer educational licenses.
