Product Introduction

Sometimes, a seemingly simple task can take months to complete. I've been searching for a solution and hope to create an adapter that can both supply filament from the AMS hub

The AMS system is extremely sensitive to the smoothness of the supply path—even the slightest resistance in the supply channel can trigger an error. Therefore, ensuring that the filament flows smoothly and unobstructed through the channel is of utmost importance. I tried various design solutions, repeatedly delaying the project schedule and constantly re-evaluating them... In the end, the design of this adapter fully met my expectations: it is compact in size, with a well-optimized geometric structure, while being fully functional and easy to use.

Materials and printing suggestions

This product is mainly printed using PETG material. I recommend using a fine-diameter nozzle

The file is provided in the .3mf format and has been fully configured in advance. Of course, you can also flexibly adjust various parameters in Bambu Studio according to your own needs to achieve the best printing effect.

Of course, you can also choose to print with a thicker layer height, and then insert highly wear-resistant materials such as carbon fiber or glass fiber reinforced filaments into it - just a few prints will make the channel surface smooth as a mirror. However, if you not only pursue functionality but also care about the aesthetics of the finished product, then using fine layer height printing will undoubtedly bring a better visual experience.

Assembly and installation of accessories

I used some basic and affordable pipe fittings to fix the various conduits. When disassembling the pipe fittings, I first removed the snap locks with rubber sealing rings. The whole process was very simple, as long as you make sure not to lose any parts. The relevant steps have been described in theThe previous videoIt will be demonstrated in detail in the middle.

Unlike my previous designs, I didn't choose to use compression locking at room temperature this time. PETG material has extremely strong thermal expansion and contraction properties - it heats up quickly, cools down quickly, and the contraction speed is equally amazing. So, I used a heat gun to gently heat the mounting holes, then applied a small amount of XY-2 plastic lubricant, and the locking buckle could easily slide in without any effort. No clamps, no pressure, just a pair of careful hands. After cooling, all components will be firmly fixed in place.

We have also specially made a short video to intuitively show the entire assembly process - it's not complicated, nor does it involve any mysterious techniques or profound physical principles. It's just a basic and reliable production process.

Practical application

The full length of this adapter is just over 5 centimeters. At first, I considered installing a magnetic holder to fix it on the printer frame, but I soon realized that a free-hanging design would allow the catheter to naturally unfold with minimal resistance and find the smoothest supply path. Unnecessary bends would only increase resistance and be counterproductive, so there's no need to overcomplicate things.

In actual use, this adapter performs flawlessly. The AMS supply channel is completely unobstructed - the filament flows smoothly like in a clean pipe, without any blockages or friction. The external supply interface is accessed from the side, precisely aligned with the optimum radius, and seamlessly integrated into the existing supply circuit.

In the end, this adapter fully met my expectations. Now, I'm also happy to share this achievement with everyone. There's no magic involved—just solid geometric design, clever structural layout, and meticulous attention to precision. Why not give it a try yourself? The manufacturing process isn't complicated, and once you experience its actual performance, I'm sure you'll marvel: this tiny adapter can deliver such a significant improvement!
