Drop CTRL mechanical keyboard

I'm trying to build a mechanical keyboard with screw in stabilizers, I've build some mechanical keyboards with click-in stabilizers, never with screw in. Somehow one of the pins of the metal top-part collides with the screw in stabilizer of the numpad "enter key". I already tried grinding of a bit of the pin that collides with the stabilizer, but unfortunately I can't make it fit/close properly. You can see that the pin of the toppart leaves a mark on the bottompart of the stabilizer, see picture 2. What am I missing? Using Durock V2 in a Dropshift fullsize V2. See pictures below, thanks in advance!

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....
