This baseplate fits the Harbor Freight medium sized small-parts organizer (this one). I took the original one piece model and cut it into 5 pieces to fit on the Bambu build plate.
The placement/orientation is as follows:
The orientation assumes the handle of the organizer is facing you.
You can superglue the pieces together but the tolerances are such that they should just press fit together assuming you use the install order of 1 to 5.
The author remixed this model.
