About This File

This fancy gizmo should really be called a Finger Rheostat because it acts like a variable resistor. You print the object in a base of PLA and an upper overhanging layer of Proto-Pasta electrically conductive PLA. Then you install it in a circuit squeeze and / or push it's coils around and they short together in such a way as to lower the resistance of the object. I used one to make a VCO and it works great!
