Bukobot V2 X-End (M3 nut mod)

thingiverse

I've grown fond of the Bukobot V2 design over the past two years, but one frustrating issue that's been bugging me is how quickly the adjustable Z endstop trigger screw wears down after months of use. The part in question is where the screw meets the M3 nut cavity, which is glued into place to provide metal threading instead of relying on raw plastic. While you'll still need to tap the screw as it enters, this mod offers a metal barrier that significantly boosts reliability.
