Lockable AMS lite PTFE tube feeder protection / AMS LITE lockable feeder

Updated 2024/11/3

Improving upon the shortcomings of the previous version, this new version is sturdier and easier to use.

Design Motivation:

The filament inlet is made of plastic. After printing each spool, it is subjected to friction from approximately 350 meters of filament (in fact, even aluminum alloys will be abraded).

This situation will inevitably cause damage to the filament inlet. As printing increases, the filament inlet may eventually need to be replaced.
PTFE tubing is currently recognized as the most wear-resistant material, so it is used as a guide.

It is also placed as close to the filament inlet as possible to avoid friction with the filament.

Even though PTFE tubing is wear-resistant, it will still wear out after prolonged use. At this time, it is recommended to pull out the PTFE tubing and cut off the abraded end.

to maintain optimal condition.

When designing a quick connector protector, I need to purchase additional parts online. This is actually inconvenient and costs more money. However, the quick connector can firmly grasp the PTFE tube.

I thought, why not design a structure that is entirely printed and can hold the PTFE tube?

Since the design is quite small, it tests the characteristics of the filament used and the print settings.

If you encounter breakage or imperfect printing.

Please use other materials for printing, or make some adjustments to the print settings.

PETG is recommended for printing because it has better bonding and resilience, but it is also more difficult to control than PLA.

Finally, if you encounter any problems, please feel free to ask questions.

Good interaction can make the design more perfect.

Thank you everyone
