This is a simple hanging filament spool roller with two versions of the support frame. One version (hanging_filament_roller1.stl) hangs on a vertically mounted bracket (like the one provided with some Creality printers). The other version (hanging_filament_roller4.stl) uses a 4 or 5mm T nut to attach to a 20x20 frame.
The roller that fits in the frames is formed from two copies of the part “hanging_filament_roller2” joined by the part “hanging_filament_roller3”, a short rectangular bar in a press fit. A 608 style bearing fits on the nubs on either end of the roller.
9/5/2021 update
I also have included an offset, 20X20 mounted, reverse bowden mount (ext rev bowden mount.stl) I use with the hanging roller used on my Creativity ELF. It uses two PC4-M6 pneumatic fittings. You probably want to drill/ream the 2mm bore to ensure easy filament movement. It is offset to avoid filament rubbing on the spool edge.
I later replaced it with a version that has the bowden passthrough at a 22.5 degree angle for better function (rev bowden mount-22-5).

Notes:
No supports are needed. Print two copies of the roller half (hanging\_filament\_roller2.stl) standing upright. Join the two halves with the small bar (hanging\_filament\_roller3.stl).
The nubs at either end of the roller are axles for 608 bearings.
The bearings can rest in the depressions on the frame without attachment, or you can add a dab of CA glue to help keep them anchored.
