I've been looking for ages for a vetical wall mount for the Lego 76328: The 1966 Classic TV Series Batmobile.
I found the one by @Yvrogne for the 1989 Batmobile, and adjusted it to fit the 1966 Classic TV series batmobile.
You will need to print 2 of them to mount. I drilled the holes 7 cm apart, for a snug fit.
The author remixed this model.
adjusted dimensions, width and height to fit the 1966 batmobile version, and to be able to mount it vertically
