These are brackets that you can attach to the wall on which you can place the Bambu Lab AMS.
The brackets are too large to print on a Bambu Lab P1 series printer, I printed them on a Mingda Magician Pro, one as the model and one as a mirrored model.
The dimensions of the bracket are 315x232x40 mm. The angle is 21 degrees downwards.
Of course you can print these brackets on de H2 series

Printed with a 0.6 mm. nozzle, layer height 0.3 mm, material PLA+
