Stoves seem to have the bad habit of loosing their knobs ;) Some days ago I noticed that my favorite restaurant's stove was missing two knobs. I therefore offered to help out and print two new ones on my MakerBot Thing-O-Matic. It was fun to model and 3D print it. I also got a free meal! ;)

• The knob is made to fit a shaft of 6 mm in diameter.
• The design incorporates a 6 mm set-screw to stop the knob from spinning

• Download the STL
• 3D print it
• Use a M6 thread tap to thread the 4.5 mm hole
• Insert the set-screw
• Fit the knob to the stove
• Tighten the set-screw carefully

Done! :)
