I needed a filament spool holder that could accommodate 4 spools for my CoPrint KCM system. The feed should be vertical into the 4 KCM extruders. I purchased a Yoopai spool holder:

However, when unloading and unloading filaments, the slck filament could go over the edge of the spool if it is fed upward or retracted downward. Then I remembered that once I've seen a PTFE guide for Pursa printers here on printables:

I designed a new handle and a lower filament guide incorporating a similar mechanism.
PTEF tubes are inserted into retaining tubes and inserted into guides, then filaments are fed into the KCM (or other application) extruders.
Though the retainers worked well for me as they are, if needed, they have grooves on the lower end and can be secured with regular PTFE clips. I've also included a simple clip, but commercially available clips are cheep and we all have them lying around.
You will need two M4X8mm (or M3X8) screws and two 4mm (3mm) T-nuts to secure the lower guide. The handle is secured with the provided bolt, which holds the OEM handle.
