Alu rail mountig: version filament guide for Ender3

thingiverse

This is a 4 pieces part you can use to mount filament guide on you Ender3 rails. Obs: You need to thread 3 pieces M5 and a threaded rod (+ 2 M5 nuts)! Since there is the OpenSCad script attached, you can easily customize it for you needs by changing some parameters or adding features. You might need to change the parameter "middle_space=-0.3;" from -0.0 to -0.4 depending your printing quality and the result you want to have. I use a thread tap M5 to mount M5 screws. Obs: Don't thread all the way if you want the assembly to grip in the rail! trick: I use a ohmmeter between the rail and the tap to tweet when I must stop threading.
