I thought those Wipe Towers you get when you print with two or more colors are interesting. I was keeping them and pulled the Brim off of some of them.
Princess Lilli the Bean of Candyland came over Sunday and I showed her Zero, the ghost dog from the Nightmare Before Christmas, the Minion cellphone holder from the Despicable Me series, Bob & Stuart Minion, and a few of the other projects we have printed. She went into the 30 year box developing next to the 3D printer and we spent over an hour building and destroying 3D Wipe Tower structures. Akin to Lincoln Logs (we are from Illinois), Tinkertoys and Legos.
After we had been building and destroying for fifteen minutes or so she asked why some had brims and some did not. I told her I had removed them from some, but not from all. "Grandpa, leave them on, they build better that way.
