After you convert to Direct Drive you probably need a new spool holder. So I made a dual spools holder for Ender 3 family (Ender 3, Ender 3 Pro, Ender 3 V2) or any 2020, 2040 profile like Prusa Bear. I modeled the holder myself and I borrow the filament guide from JCOENG.

BOM: 2 x M5x12mm socket head cap screw + 2 T-Nuts (M4x12 screws will probably work also)

Print orientation should be like this without any supports. Perimeters: min 4, infill: min 25%.

You can use a zip tie to secure the filament guide if your material is too elastic.

UPDATES
02.03.2023 add a new filament guide in an upper position. Useful if you print model higher then 200mm.
