Maytag / Whirlpool Washer & Dryer Knobs

These knobs can replace both the large and small knobs on a Maytag or Whirlpool washer and dryer. 

Backstory:

My large timer knob cracked on my Maytag dryer after only two years of use. On removing the broken part, I find that the knob was really flimsy - injection molded ABS plastic, with a shaft of less than 1.5mm. 

Now, can I purchase a replacement ? Yes.

Am I willing pay $20 and line dry my laundry for the 3-4 days it takes to get here ? Heck, no.

3D printer to the rescue!

Installation instructions:

1. Pull off old knob. 
2. Flip it over and check the part number on the underside (W11328381 or W11398762).
3. Print knob that corresponds to that number.
4. Orient new knob to nylon shaft.
5. Gently push new knob into place on shaft.

Voila! Should last for years. If it doesn't, you can replace it with fifty cents of material and an hour of print time. 

Printing instructions:

Shown in Prusament PLA Oh My Gold. I used the octogram spiral pattern on the bottom layer to enhance the effect of the silk / metallic PLA. Sliced for MK4S, but fits most build plates / printers.

No supports, or rafts required.

Final note:

It's a little shocking how skimpy the main piece that holds the load on the original part really is. There is easily room for 3mm of material, as designed here  - the difference in cost in ABS plastic is less than a penny.  If this is how dryer knobs are made these days, how am I supposed to trust the manufacturing quality of a microwave ? Scary.
