This is a plug for the headrest on my BMW i4. the visibility out of the rear window is limited with the middle headrest which I don't normally need. instead of an empty hole, I designed this plug to make it more attractive. it probably fits other BMWs but I have not tried.

CAUTION: this is not a replacement for a headrest. if you intend to have a passenger at this position, you need to have a proper headrest to ensure their safety.

NOTE: I used ABS as it is the same plastic used normally. it has a high melting temperature. PLA is likely to melt or break in the vehicle and will be next to impossible to fix or remove.

DO NOT USE PLA. it will get soft in the heat of the vehicle. if it breaks in your headrest post you will not get it out. ABS is the material normally used in automotive applications
