Very simple clip to disable the oscillating function on my Honeywell desk fan. Clips onto the knob (very firmly!) and prevents the knob from vibrating its way into the oscillate setting.

Notes:

* Probably clips *too* firmly, it doesn't flex much at all even with PETG. Barely snapped on, will likely need tool or break something to get it off
* While the tall part of the clip fits the back of the knob just about perfectly, the cutaway from the bottom of the short side is too aggressive
* However extending the front clip prongs to be taller would also make them stiffer
* Possible solutions include thinning the walls, thinning just the prongs, or making the open cut more aggressive so it doesn't need to flex much
* Either way, it suits its purpose at the moment and prevents fan oscillation, ever.
