The author remixed this model.
I modified erajompp's original trofast support for attachment by glue rather than screw-in. I added an inset channel on the glue side intended to capture any excessive glue application and prevent it from squeezing out past the edges of the bracket.
To install I used a single bead of medium viscosity cyanoacrylate (aka super glue) on the glue face within the bounds of the inset channel.
I'm also including my f3d file so you can make easy mods to the geometry in Fusion 360.
