Remodeled with the same idea as the profile mount, but it has two screw holes so it can be mounted horizontally with minimum footprint, while still retaining strength.
My print is in resin, 100% infill, I've since switched to a FDM printer but didn't have the chance to reprint it yet. It should hold the Index fairly well in PLA too.
I suggest printing it with at least a 30% cubic infill and minimum of 3 walls to be on the safe side.
