Honestly, unless you’re a professional painter, the result is guaranteed to look much worse than just looking at a white E1 against a brown frame. And even trying to 3D print a replacement housing usually ends up with a surface finish that looks worse than the original white plastic. I also haven’t seen replacement housings sold anywhere separately either.
That’s true. However, I have a triple window with three roller blinds, and the middle E1 driver has to be mounted on the window frame anyway. That’s why I’d love to find a safe way to change the housing color to better match the dark brown frames.
As ott_silver already mentioned, that’s probably going to be a challenge. I’ve tried touching up a damaged spot on a window like that before, and there are wax kits available where you can mix different shades. But it’s really hard to get the exact shade right.
Remove the four screws and carefully take off the back cover. The internal components are simply plugged in and can also be carefully removed. Only the circuit board is secured by plastic tabs, which must be carefully pushed back, leaving you with the bare plastic housing.
But please note: opening the device will likely void the warranty.
Just keep in mind that spray painting over unknown plastic without proper prep and a dedicated plastic primer is pretty much a lottery. It might hold up, or it might start peeling off in sheets sooner or later. If you do go for it, make sure the surface prep is spotless!
