Fan Heater Replacement Control Knob or Switch

thingiverse

I recently acquired a brand-new heater that arrived with a faulty control knob. The vendor generously provided a replacement and declined my offer to return the broken one, resulting in me having a fully functional heater minus a single component. This is precisely what 3D printing technology is designed for! After conducting a brief search, I discovered a heater fan knob design with adjustable parameters that could be tailored to suit my needs. To achieve my desired outcome, I merely needed to add a few lines of code, which served as an excellent demonstration of the technology's capabilities. Many thanks to Maurerpe for the initial guidance. If you're unfamiliar with OpenSCAD, download and explore it – this versatile tool is ideal for projects like these. Simply load the SCAD file from here and navigate through its intuitive interface; I've carefully commented each section to facilitate your understanding. You should be able to create basic designs for D-shaft control knobs. Instructions: Measure your existing or broken knob, or the heater/device in question. Add the dimensions to OpenSCAD at the top, where each parameter is thoroughly explained. If you're unsure about any setting, experiment with different values (click PREVIEW) and observe how the preview changes accordingly. Once you've made the necessary adjustments, Render and Export STL. Proceed with standard print operations – slice and print – or send the STL file to a print hub for further processing. I hope this information proves useful.
