What is SpaceFN and why you should give it a try
The SpaceFN concept - setting up your space key as a layer switch when held - is probably one of the most useful tweaks in the keyboard hobby. Let me explain how it works. My SpaceFN article on kbd.news made some rounds recently - quite surprisingly given the age of this concept. This piece you're reading is a condensed version of the full post. If you're left with unanswered questions, you'll most likely find the info you're looking for in the original write-up. On my imaginary top list of the most useful keyboard features, tweaks and hacks, SpaceFN would deserve a podium finish for sure. But what makes it so special? In short: SpaceFN is easy to implement, easy to learn, costs nothing, can be used with any keyboard, and can improve your productivity instantly. I will list its benefits below, but can state right at this point that the SpaceFN concept, setting up your space key as a layer switch when held, is clearly one of the most useful tweaks in the keyboard hobby....

Hmm... it's new that Keycappie's head is loose. The switch came with the Keycappie is just a normal switch. So other switches should be fit...
If it's too loose, how about painting white? Or clear coating or something. The thickness of the paint will fill the gap between the hole and the switch.
I know it's not a elegant way, but I have done that on Cherry MX joint, when I make a keycap with 3D print. I used very thin clear-coating, so I have to spray it a few times but finally, it worked.
