6.5' speaker adapter for BMW vehicles

thingiverse

This is a custom 6.5-inch speaker adapter designed specifically for the BMW E46 model. Two distinct variants are available: one features a ring around the speaker, while the other boasts a minimalist design with a bare 4mm height. I personally opt for the latter and have found it to be completely satisfactory. When creating this adapter, I employed a combination of infill at 20% density and a layer height of just 0.2 millimeters, resulting in a remarkably solid and durable end product.
