Printrbot Z Probe Thumbwheel

Designed to trap original nuts without washers. Printed @ low infill to allow slight compression on thumbwheel mating surface producing tension preventing assembly from loosening or not, only time will tell.

If you're not able to figure out component orientation from photo, you probably shouldn't be 3d printing. Yup, I know there is banding on shown example...am working on Z axis to resolve that.
