Flanged Fillament spool holder Direct Drive Ender 3

thingiverse

I found that the original main tube for the spool holder had a tendency to let the spool slide to the side and eventually fall off of the bearings and onto the spool nut. The flange on the sides should prevent the spool from moving too far in either direction while still being easy to add/remove. I used this tube with 2x "spool nut with bearing support" nuts and two 608 bearings. None of the other parts from the initial filament guide were needed besides the two mounts. Tip: I found that you need to use 4x m4x16mm screws with T nuts to attach the mounts to the 1010 frame.
