A small PCB - Standoff which uses a m3 Heat-Insert Nut. It also features 4 holes to attach to basically everything. You could also Glue it of course.
The m3 Insert i used is a M3x5,7mm Brass Heat Insert made/sold by Turmberg3D. (Bought of Amazon.de) But other ones with similar dimensions will fit as well. The hole for Insertion is 4mm wide.
Happy Printing :)
