Three fulcrums to hold a 1/4" square dowel
thingiverse
I designed these three different fulcrums to hold a 1/4" square dowel to balance atop a vertical dowel when using the Tinkering Studio's Open Kit exploration of Balance: https://www.exploratorium.edu/tinkering/projects/open-kit-balance This way, students can move their fulcrum to the middle or off center without gluing or ungluing the balance point from their square dowel. I used Tinkercad CodeBlocks to design these three shapes, and I 3D printed using an Ultimaker 3 Extended.
