CR-10 Smart Filament Guide
thingiverse
The First Creality CR10 Smart machines came with a filament guide to bridge the space between the runout sensor and the extruder. Unfortunately Creality supplied the guide from a different machine so I dug out Fusion 360 and designed my own. Probably far from perfext but this works for me. I suspect the angle at the back is a bit off but it's close enough and saves fiddling the filament through both entry points in the loading chain. Note: this works with the original extruder on the Smart, If you've fitted a replacement all metal one (you should) then entry hole is usually higher than the stock extruder so this won't help.
