About this part

The creator describes adapting the Blaupunkt mounting holes, sizing the speaker holes for M4 heat-set inserts, and printing the adapter at 180% with supports; an optional Dampener.stl is provided for printing a gasket from TPU. PETG or ABS are engineering-inferred materials for the rigid adapter; TPU is creator-specified for the optional dampener.
