This set is for makers using the Maker Studio construction system.
There is a Measuring tool to make sure the holes you make are on center and even. A Remover tool to pry off stuck parts or push rods through holes. And a Gripper tool for grabbing the rods or safely push them through tight holes.

It is printed on a 100 mm square printer bed. I used 6 perimeter and .015 build height. DO NOT change orientation of the parts! They are set for maximum strength and won't break this way.
