Ender 3 Bowden Tube Filament Guide for Top Mount Extruder

thingiverse

Mounts on the end of the top rail of Ender 3 or similar V rail Mendel style printers, providing a filament guide for rear/side mounted spool holders into a bowden tube. I am using it with this spool holder mount https://www.thingiverse.com/thing:4333835 and this top extruder mount https://www.thingiverse.com/thing:4750003 with the BIQU extruder (which has a bowden tube input). There are two versions. The standard version is for the type of coupling with a large tapered thread and allows the bowden tube to go all the way through (commonly used on the hotend), the M6 version is for a smaller brass M6 coupling and includes a guide to cut a length (18mm) of bowden tube to put inside before screwing in the coupling. I've tested these with PLA and they worked out fine, I used tree supports for the part which presses into the V-slot extrusion end, the tapered coupling is quite hard to thread in but I managed it by pinning the part down with my a Power Fister 20mm spanner (https://www.thingiverse.com/thing:4750787) and using a small spanner on the coupling
