Your PTFE Clips just got better.

3 grams of material, 14 minutes of print time, try it out! *Use PETG or greater.

Update 3/15/2024: 

If you attempt using similar Tool Head PTFE Guide like this one by @AdamL

You may try skip the 3rd clip and relocate other two clips as the picture shows.

Have you ever realized that you shouldn't force the PTFE tube into a fixed position?

The curve of the PTFE tube constantly changes as the toolhead moves from corner to corner. Just follow the curve!

With three different clip shapes, each designed for a specific position. The PTFE tube can now move more freely inside the clips, with only necessary restrictions and no unnecessary forces.

仔细观察，工具头移动时，PTFE 进料管的形状会一直变化，并不是完全贴合链条，使用三种不同形状的固定夹可以使得进料管受限的移动，与此同时又不会使其受到太多强制的力。
