I saw Beetleblocks today in a Tweet from Eric. (Eric, I met you at CMK 2013.)
I've been using Scratch with students since 2007.
I was getting ready to do some 3d printing with my students, and discovered that 3dTin--the modeling software we used last year is no longer available. Before setting up user accounts in TinkerCad, I thought I'd check this out first.
I'm curious to learn more.
Thanks!
