Is the control knob on your Holmes space heater broken, loose, or missing? Instead of throwing away a perfectly good heater, bring it back to life with this custom-designed 3D-printed replacement knob.

I originally created this part to repair my own Holmes portable heater after the knob cracked. This replacement knob is designed to fit standard D-shaft heater controls—the same style commonly used in many Holmes models.

The knob installs in seconds: simply push it onto the heater’s D-shaped control shaft and you’re back in business. No tools required. Printed with high-quality PLA for durability and a snug fit, this part offers an easy and affordable fix that can extend the life of your heater by years.
