P1S AMS T-pose support

A parametric support plate assembly for Bambu Lab P1S 3D printers, consisting of three dovetail-jointed plates (left, center, right) that hold dual AMS filament systems in a T-pose configuration. The plates feature X-braced windows, dovetail slots and tongues for sliding assembly, and mounting tabs for printer edge engagement. Four triangular side supports with screw holes secure the outer plates to the printer frame, while seam strips with countersunk screws lock the plate joints together. All dimensions—plate width, depth, thickness, window size, brace width, joint geometry, support reach and drop, and tab/hole sizes—are fully adjustable for fit to different printers.
