Ender 3 (or generic 40mm extrusion) Z braces/supports

thingiverse

Ladies, Fellas, Those that know better: you ever want a bit more stiffness? just enough clearance for a glass bed and for a covered control/screen pcb. will interfere with zstop, so unless you're using BL Touch you'll need to readjust the file in openSCAD or only use a brace on the right side. designed for use with the following t-nut design https://www.thingiverse.com/thing:2881180 includes modified openSCAD file used to output this STL each brace will need: 8x m4 nut 8x m4 t-nut print (if you just have real m4 tnuts laying around i'd just use those instead) 8x m4x10mm screws (holy cow i need to dust the undercarriage a bit)
