Cooker & Hob Replacement Knob + Ignition Button

Cooker & Hob Replacement Knob + Ignition Button

This is a replacement knob designed for the front or top of your cooker hob/stove, along with a matching ignition push button.

⚠️ Please Read Before Printing

There are two main knob orientations, so Please make sure you choose the correct version:

• Top-mounted hob knob → dial faces RIGHT
• Front-mounted cooker knob → dial faces UP

Depending on your cooker model, the shaft the knob fits onto may stick out more on some appliances (sometimes around 6 mm). These knobs are designed to fit securely either way, but in some cases you may want to add a small amount of glue for a tighter hold.

Test Fit (Recommended First Step)

A test square is included to check compatibility before printing the full knob.

• Internal “D” : 6 mm × 4 mm

Steps:

1. Print the test square first
2. Push it onto your cooker’s fitting
3. If it fits → you’re good to go, print your knobs
4. If it doesn’t fit → scale the test square in your slicer and reprint

Once you find the correct scale:

• Apply the same percentage scaling to the knob

Example:
If you scale the test square by +1%, scale the knob by +1% as well.

This step helps avoid wasting filament and time.
