This part broke on my microwave and a replacement is about ~$60 here in Canada (slightly cheaper if if I order it from the US). I decided I would print my own, and hopefully others can use this as well.
My microwave is a KCMS1555RSS but this should fit any microwave that uses this part. As far as I can tell, these are the part numbers used by KitchenAid and Whirlpool for this part:
- WP8205451
- W10298900
- PS11745265
- AP3776470
- AH972837
and it should be compatible with any of these microwaves:
KCMS1555RBL0, KCMS1555RBL2, KCMS1555RSS0, KCMS1555RSS2, KCMS1555RWH0, KCMS1555RWH2, KCMS1555SBL0, KCMS1555SBL1, KCMS1555SBL2, GT4175SPB0, GT4175SPB1, GT4175SPB2, GT4175SPB3, GT4175SPB4, GT4175SPQ0, GT4175SPQ1, GT4175SPQ2, GT4175SPQ3, GT4175SPQ4, GT4175SPS0, GT4175SPS1, GT4175SPS2, GT4175SPS3
Printing instructions
Print all parts in their default orientation
Main body:
- Layer height: 0.12mm (or whatever the lowest setting is for your printer)
- Speed: slow - this helps give the part extra strength
- Temperature: depends on your filament, but ideally near the higher end to improve layer adhesion strength (I used 230C with PLA filament)
- Walls: At least 1.2mm
- Infill: 10% or so is plenty
- Supports are necessary
Reinforcement panels
These parts are not as sensitive to printer settings, my only suggestion is to make sure they are completely solid (they're small enough anyway)
Assembly
There are three parts. The main body, then 2 reinforcement pieces that reinforce it so it doesn't rely on layer adhesion of the long “wall” part of the lever. They only fit cleanly one way, and they're just glued on (I use wood glue because I have it on hand, but whatever your favourite glue is for 3D printed parts should be fine)
The reinforcement pieces may not be needed, I don't know, I didn't test without them.
Results
I've been using this for a few weeks without issue. Hopefully it lasts several more years so I don't have to open this all up again. Installation was straightforward
Modifications
If you find that it doesn't quite fit for you (e.g. due to printing tolerances or whatever), then I have included the FreeCAD project file. It's mostly parametric so shouldn't be too hard to adjust as needed.
