Pluggable PTFE Tube Connector (No Material Jamming, Can Be Used as an External BMCU Retraction Buffer Component)

Three versions of the PTFE connector have been designed, and it's finally close to perfect.

Note:

1. The male end ("convex" shape) is the direction of the feeding material, and the female end (equally wide cylinder) is the direction of the material output. Accurate alignment prevents material jamming.
2. If there are tolerances, you can enlarge or reduce the print by 1%~2% as needed.
3. When downloading the model (STL) file separately, do not select random "seam" for printing; otherwise, the two ends may not be able to connect correctly.

This connector has the following features:

• No material jamming: Typically, pneumatic head connectors and the like related to PTFE are very prone to material jamming. This connector has been specially optimized for the feeding direction, and the feeding material will naturally align with the middle of the tube, making it very smooth.
• Tight fit: Hard materials are difficult to clamp PTFE or too tight to insert. This design addresses the soft properties of PTFE with a targeted locking mechanism. Easy to insert into the tube and secure.
• Pluggable: It can dynamically connect to different material tubes, and after connection, it can be locked to prevent easy detachment.
• Retraction buffering: If it needs to be used as a material retraction buffer, simply cancel the docking when printing.

In short, this connector can serve as a perfect low-cost retraction buffer solution, and it also minimizes problems such as pneumatic head material jamming, while also offering convenient switching in a multi-material environment.
