Apollo Spacecraft Extruder Knob

I found this knob somewhere - probably on a NASA site. It's a model of the switch knobs used in the Apollo Command Module Spacecraft. The original is about 2 inches in diameter, designed so it can be used while wearing spacesuit gloves.
Scaled down to about 1" and with a D-shaft cutout, it works great as an extruder knob for my Ender 3 printer. Printed in silver PLA.
Will probably fit most anything with a D-shaft
