Husky Portable Air Tank Replacement/Upgrade Tap Knob

I bought a Husky 10 gallon portable air tank from facebook marketplace a while back, but the plastic knob that switches on and off the output was split making it hard to operate. 

So I designed this replacement,  It has a larger diameter than the original and a much more ergonomic shape.  It is also much more substantially made, so I doubt it will ever break again.

I printed it  in PETG-GF at  .16mm layer height but pretty much any material and print settings will work I reckon. 

There are lots of other portable tanks that have very similar looking fittings that may very well be able to use this.  I have included the Fusion 360 file, the critical dimensions are parametric.
