Stantion Centering Knob

Centering knob for Stantion Mini Head Control Panel. Control Panels are missing the centering knobs, which is very annoying to use a screwdriver to center during the show.Decided to make a knob. It should fit snug, radius of the model is almost perfect so the “tongue” inside the knob can be misaligned and it will still fit snug.This part is very small so I believe 0.2 nozzle is a must, print with very slow speeds ~40-50 (worked best for me).Please feel free to tweak or change this model.
