PTFE Filament Funnel

This is a filament funnel I designed for myself. I wanted to share it so others can benefit from it. I hope you enjoy it. Please remember to push the PTFE completely into the funnel. Make sure you cut the PTFE at a perfect 90-degree angle and make sure there are no burrs around the cut area. Otherwise, it can make it difficult to insert it into the funnel. Cutting it crookedly can cause the filament to get stuck while pushing it through the funnel. Update: I've received some feedback that the PTFE is loose when inserting it into the funnel, causing the funnel to fall off. Therefore, I've lengthened the PTFE inlet of the funnel slightly and narrowed it to hold it tightly. You may have some difficulty inserting the PTFE. Please be patient.
