4mm hexnut retainer for aluminium profile
thingiverse
Holds a 4mm hex nut in place inside an aluminum profile. I used this on my X-axis profile to reverse the direction on the POM wheel bolt so the nut was captured inside the profile instead of the bolt head. The profile is partially drilled out so it's impossible otherwise to keep a nut in place. This only holds the nut in place. when the metal plate is installed the nut will be pulled against it when you tighten the bolt.Installing the dual-z mod by proper printing the nut would be in a recessed area inside the bracket which was almost impossible to tighten. Once the retainer is in place I could put the locknut there. This is the POM wheel with the off center nut to tighten the wheel.For "Ender 3 dual Z axis with optional frame braces" by ProperPrintinghttps://www.thingiverse.com/thing:3746653
