Fokoos Odin-5 F3 Reverse Bowden Filament Guide

https://youtu.be/1wWPUGzpIGc

I designed these two options (and working on a third style) to hold a PTFE tube as a reverse bowden filament guide for my Fokoos Odin-5 F3s. I have a filament dryer next to the machines and want to have the PTFE guide the filament out of the dryer and into the extruder. With a decent piece of PTFE, it will have enough reach to guide the filament throughout the height of the Z axis.

There are 2 styles (A and B). The first (A) requires you to remove the M3 screw holding the fan shroud and replace with an 8mm M3 screw. The second (B) does not require removal of anything--it just holds over the two bolts holding the extruder carriage to the X Axis. I designed style B to have slightly larger than needed cutouts to allow of the bridges at the top of the cutouts not being perfect.

I designed the pieces to print without supports. As it prints for me, the PTFE stops at the bottom of the guide cylinder and stays in place. I liked the idea of keeping the tube off the extruder and seeing a little of the filament feeding in. I also did not want to physically connect the tube (pneumatic connector) and add additional weight or complexity.

I have named them v1.0 as I believe this is now a reliable design. However, I anticipate some suggestions and feedback and may later create updated versions. So, please let me know what you think. I am trying to work on style C which would fully clip over the extruder mount carriage and be more solid than style B. We shall see... I prefer style A personally and am using that one on my Odins.
