Ender 3 Top filament guide funnel to bowden tube guide.

thingiverse

This is the top half of a guide designed to reduce the stress on the filament as it passes from a top mounted spool into the extruder. This can be used alone with just filament, or used in conjunction with a bowden tube mount between the extruder mount and this top guide. I will link to the extruder mounted bowden tube attachment that I use which is a remix of another. This guide is original. There are 3 files. The original is the FunnelGuide3_wMount I made a change to this with FunnelGuide3_woMount + Top Side Mount that allows significantly easier printing. I suggest printing and assembling this way. The side mount or the original has space for a screw and nut you can find holding many components on, those can also be 3d printed with some success as well. The side mount itself was a remix from this design: https://www.thingiverse.com/thing:2917932 Printer: Ender 3 V2 Support: Non on the main piece, with tree support on the top side mount. Infill 25% (this could likely be 10% or less)
