The switch/toggle will be stuck after print, this is normal, you'll need to “break” the toggle from the axle. It should not take a ton of force and should be done using just the strength of your hands. The switch may be a bit stiff at first but after a bit of use it will smooth out.
Added loose version like what was available on the original model for those who may be having issues with the toggle fusing to the body. It is a little less clicky than the regular version.

The author remixed this model.
This is a taller version of the original Print-in-Place Fidget Toggle Switch. I had a hard time using the original design with one hand so I added a grip on the bottom that makes it easier to hold.
