TinkerCad is ending in a few months.
In a very real way I owe TinkerCad for Joe's Makerbot. My boys love TinkerCad. But with TinkerCad's recent switch to a very prohibitive paid model it was difficult to continue recommending them. And now they're ending. Part of me wishes that someone will buy them up and keep it going, maybe make a slightly more accessible paid model. But for now this is the state of events. Sad.
