Courtesy light switch mount (3d printed or print file) for TOPPER?

The $300 (discounted!) price of the official GFC Topper light kit is insane. And they use tiny and vulnerable inline switches and two colors, which I do not want.

I plan to add four white marine led lights

and a Blue Sea waterproof spst switch and waterproof fuse holder.

Total cost, except for wires and splices , is $40.

I was wondering if anybody has a 3d printed switch mount or just the STL file to mount one up HIGH in the upper left corner of my Topper, close to the rear hatch opening? A surface mounted box on the bottom of the roof panel close by could be acceptable. (The GFC third brake light wires are circled in red, ignore those):

I prefer to mount it up there so it cannot get turned on or smashed accidentally. I use my bed for truck stuff, I don’t camp in it!… I can easily print it in ABS if I can find a good file. Any comments will be welcome.
