3D model description

Yet another knob for turning axles.
This one is replacing the four broken Scope Knobs of my Tektronix TDS 220.
It has a 4.8 mm axis and my knob fit's as good as the original one.

They got old and the plastic softener is not enough anymore to withstand the strength of my fingers :)

Designed from Scratch with FreeCad.

Using a trick to get the diameters correct although printing tolerances:
3 "fingers" build up the pressure to a Plate to hold the knob in place.

Just some 30min work.
