I wanted to find a M.2 bracket for my Latitude 5480 and I found one on thingiverse made by Allotrope. I remodeled it to be able to print it without supports. I used an m2 x 4 screw to screw it into position and used an M.2 screw to hold the NVME in place. I would only screw the M.2 screw to be snug or else you risk stripping the threads in the plastic.
The author remixed this model.
Made it print with no supports and cleaned up some geometry.
