Single Filament Entry with Fitting – A1 / A1M

This model replaces the original AMS hub on the Bambu Lab A1 or A1 Mini, just like the direct-feed version, but includes a hole designed for an M6 pneumatic push-fit connector, allowing you to use a single PTFE tube. It’s an ideal solution if you’re not using the AMS but still want a guided filament path. Particularly useful when printing flexible filaments like TPU, as it helps reduce friction and bending during feeding. The hole is designed for a standard M6 thread, but it can be adjusted by scaling just the hole area in your slicer or modifying the model before printing to fit other connector sizes. For installation, follow the step-by-step instructions shown in the attached GIF. Boost MeIf you like my work, you can support me by giving it a boost; it’s free.or even by buying me a coffee
