Description

To make filament loading easier and reduce the drag on the filament I designed this PTFE guide. It is designed for the original reverse bowden tube which has an outer diameter of ~4.4mm (instead of the normal 4mm).

I would not recommend to print this on a FDM printer. It was designed with MJF in mind. But I guess SLS or SLA will also work. I like that the texture of the dyed MJF part matches the texture of the hotend assembly.

This guide requires you to either remove the lid or raise it by at least 30mm.

_______

I added a second version for standard 4mm bowden tubes. However, I haven't tested the fit on this version.

The modeled hole diameter for the Snapmaker 4.4mm tube ist 4.8mm and for the standard 4mm tube it is 4.4mm. These tolerances worked well for the model I got printed in MJF.

I also uploaded .step files for each version.
