TPU filament feeding bracket, 3KG filament bracket, for P2S, P1S, X1, etc.

According to Bambu Lab official statements, for XYZ 3D Printers such as P2S, P1S, and X1, when printing TPU material, it is recommended to use the shortest filament input path to prevent clogs and breaks.

Therefore, the best feeding solution is to place the filament on top of the 3D Printer (with the glass lid removed).

Note that a 5cm PTFE tube can be added or its length adjusted according to your needs. Based on my tests, I recommend adding the PTFE tube as it provides some buffering during rapid hotend movements. If it's too short, there won't be enough buffer, and rapid pulling will cause a lot of filament stringing.
