About this 3D model

I've encountered several challenges when feeding filament through the AMS while printing in multiple colors. Frequently, the filament becomes obstructed in the buffer region and subsequently rewound. To address this, I manually handled the filament (detaching it from the printer) and observed that if the infeed tube isn't perfectly aligned during insertion, it triggers a rewind after a brief pause. To rectify this issue, I 3D Designed my take of a Ptfe guide (there are others out there but this is my version) to, ensure proper alignment. This modification has significantly improved my printing experience, and I've had no further issues with color changes. v2.1 update: I have now created a no support version which only requires a brim ! additionally i have added Chamfers to both in inlet and outlet to be more smoother
