What a gridfinity 4 × 4 baseplate that fits the bambu lab a1 mini is

A 4 × 4 Gridfinity baseplate, 168 × 168 mm, that prints in one piece on the 180 × 180 mm bed of a Bambu Lab A1 mini. It uses the standard 42 mm grid with the 4.65 mm tall profile, has optional 6 × 2 mm magnet pockets and an 0.8 mm chamfer on the underside so it does not rock on a drawer bottom. Print flat in PLA.

A 5 × 5 plate is 210 mm and will not fit the A1 mini; tile several 4 × 4 plates instead. Open the plate in SpeakCAD for free, change the grid in the chat or the viewer, then download the STL.
