BMW Headrest insert plug

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.
