The resistors are standard 3W resistors.
The cables are routed through the housing through a slot, which i melted into the plastic with a heated exacto knife. This also serves as a strain relief.

The body already includes the dial, but there was a typo and I was unsatisfied with it in general. So i made a separate dial, which is sandwhichd within the body and switch nut.
