BMW F20 Front Door Speakers (10cm - 100mm) to Dayton audio RS100-4 4"

thingiverse

PLEASE USE V2.1 as reference! This is a design i made from scratch for a BMW F20. In case you want to make one yourself: speaker mount hole 1-2 ~118mm hole 2-3 ~90mm 3-1 ~90mm Print V2 with supports, V1 just is basic (do note that the mounting holes in V1 and V2 blank are TOO SMALL!) Do note that it is a 4 inch speaker, but with a small inner diameter, so it won't fit all the normal 4 inch speakers. https://www.daytonaudio.com/product/89/rs100-4-4-reference-full-range-driver-4-ohm
