The file 'Luggage Rack Bracket For Rear/tail Light 3D Printer Model' is (stl) file type, size is 13.2KB.
A clamp to attach a rear bike light to an older style luggage rack.
Fits racks with 8mm bars, approximately 85mm centres. There is a few mm of play either way. If not, stretch/shrink objects slightly or use a dremel. 'socket' for the light's clip is about 9mm across.
Use a fair amount(40% seems good) of infill and perimeters for strength.
Screws are about 3mm across the thread and 11.5mm long. No idea what their size is.
Photos show a slightly older version with holes filled in with nail polish, model changed to make the top screw holes blind so this isn't needed. Original version had the screws coming in from the top, new version is more annoying to install but keeps water out of the screws.
