ESB tanning bed mechanical timer knob.
This version is a 3D printed knob and made to compensate for the new style of mechanical timer where the stem is rotated 90 degrees.
Basically, if you have an older ESB Tanning Bed with a Faucigny timer and you replace the mechanical timer with the new AFTERMARKET timer, now your timer will point at the 3 o'clock position when off. With this 3D printed replacement knob installed, now it will point at the 12 o'clock position again.
Knob is made with ABS plastic. knob color may vary.
