Broken Stove Knob Collar Fix

thingiverse

I am sharing this information not for you to download, but to show you a better way to fix a cracked or broken stove knob instead of printing an entire new one that doesn't match. My Jenn-Air stove had several stove knobs with cracked and crumbling female D-Shafts, making replacement expensive compared to my solution. I printed these collars to match the 10mm outside diameter of the stove knob female shafts. The fix is to slip the collars over the cracked and split shafts to force the split in the female shaft back together. One of my stove knobs had been split so badly that a piece had fallen off, but after reassembling the broken piece onto the shaft and pushing a 3D printed PLA collar over it, the shaft now works like new, more than 1-1/2 years after I created this as my first fix with my Anet A8. There's no wobble whatsoever. This collar slips over a stove knob with a 10mm O.D. female shaft. Measure the O.D. of your stove knob shaft to make scaling adjustments for other shaft sizes, or create your own collars. Making a hole through a cylinder is a perfect first 3D design exercise to create your own collars. Putting these collars on your existing stove knobs is a good preventive measure to keep them from breaking in the future.
