I agree! The only annoying thing with the lego pieces is that they don't friction hold on and can easily slide off. You might be able to fix that by wrapping the knob in some painters or electrical tape and squeezing on the lego piece.
My 2nd batch K.O. came with a black nub on the slider that suits me just fine. I didn’t even bother with the knob they provided with the slider. My K.O. works. Why press it (pun intended) for aesthetics?
Thanks for sharing your approach! While modifying the knob's opening may have worked for you, it's essential to proceed with caution when making permanent adjustments. Alterations can sometimes affect the functionality. In my opinion, unless you are confident that you will not screw it up, staying away from filling down the knob would be a more sound choice.
While dish soap may seem like a cost-effective alternative for lubricating electronic devices, it's not recommended. Dish soap is conductive, can leave a residue, and may contain corrosive elements, posing risks of short circuits, interference, and damage to the device. Using a lubricant specifically designed for electronics is safer and ensures proper functioning without compromising the device's longevity.
