“The goblin engines, though minute and ramshackle, are no less dangerous.”

—qie Zi, The Art of Seej

The Marshmallow Mangonel evolved after a Twitter conversation with a educator who’s interested in bringing Seej into the elementary classroom. The Penny Catapult and Penny Ballista can pitch a penny with enough force to make a second grader cry, so kinder and gentler ammunition was clearly needed.

The outer edges of this engine are beveled a bit so that it’s easier on little hands.

The side braces are designed to fit on smaller build platforms like those found on the Printrbot Simple and Makibox.
