Anycubic Mega S extruder intake with bigger bore --> easy filament change possible

thingiverse

This is a very simplistic customizer for the intake guide of the Anycubic Mega S extruder. It happened to me very often that I couldn't change the filament properly because it would get stuck in the extruder (see picture), even if I preheated and pushed a bit before pulling it out. The reason is that the bore is too narrow (approx. 2mm) -- at least in my eyes. I propose to use a 2.5mm bore. Then changing the filament will work properly. So far I didn't notice any negative effect of the bigger bore -- except that you have to be slightly more careful when inserting the filament (in order to find the bowden tube). If you want to adapt the design to your own needs (e.g. adapting outer diameter, bore diameter), please follow these easy steps to get the STL file you want: 1. install openSCAD: https://www.openscad.org (it is free of charge) 2. open the scad file of this thing 3. adjust the parameters as you like (height of the pile, etc.) 4. render the design by pressing F6 5. export to STL by pressing F7
