Shower Knob for Moen

Got annoyed one day that my Moen shower knob snapped for the 2nd time and so I created a beefed up one for 3D printing. In retrospect I probably just needed to replace the stem and/or lubricate it a bit but oh well.  

Unfortunately I couldn't find a picture of the latest version I ended up using - and they're at my last house I no longer own.
