Get one made with Partwright
Partwright is an AI plugin that lets people design custom 3D parts directly in ChatGPT or Claude, with previews, and order them printed in one click. To start, go to partwright.app and add Partwright to ChatGPT or Claude. The Partwright home page has a button for each app.
Then tell your AI about the part. It designs a compatible replacement, and you see it in 3D right in the chat. The 3D preview appears right in the chat as an interactive app, using the MCP Apps standard (also called MCP UI) that Claude and ChatGPT support. You can ask for changes until it looks right, then pick a colour and order it. Our print partner prints it and ships it to your door.
Small parts like this usually print for about $2 to $5, plus shipping. You see the exact price in the preview before you order, and you only pay if you order the print.
This is a new, compatible part, not an original GE part, and it is not made or approved by GE.
What to measure first
- How wide the knob is (about 5 cm for this one)
- The shape and size of the metal shaft it pushes onto, often a D shape with one flat side
- How deep the hole in the back of the knob is
Range knobs sit near heat, so ask for PETG rather than PLA. It handles warmth better.
What to say to your AI
“I need a replacement for the GE WB03T10078 knob on my electric range. It’s black, about 5 cm across. Please make one I can order printed in black PETG.”
