Honeycomb Shelf Bracket

thingiverse

A simple shelf bracket I designed for use in my home office, according to Fusion360's static load analysis tool this shelf would be able to handle 1000N of static load force (roughly 210lbs) per bracket if it were made from injection molded ABS, results will vary wildly with 3D printed materials, however I've been able to achieve over 100lbs of load on these with carbon fiber PLA as long as you print them with enough perimeters to make the honeycomb solid. I would recommend using a minimum of four perimeters with a 0.4mm nozzle, and twenty percent infill. Eventually, I'll do a full deep dive analysis of load ratings based on print settings and materials, but in the meantime they work really well, look great in my opinion, and fit on most printers pretty easily. Space the brackets every sixteen to thirty-two inches or centered on wall studs and drive two screws from the top of the board into the brackets to hold the shelf in place. I did sixteen-inch spacing and a one by twelve plank for the shelf in my office. For updates on future data regarding these shelves, check us out on Instagram, @vincent.teune After initial testing, the weight limit of these brackets is still undetermined. I printed out a few brackets with fifty percent grid infill, three perimeters (so that the central honeycomb is solid) and printed in SunTop Carbonfiber PLA, and they withstood 115.8lbs of static load for ten minutes without suffering any plastic deformation. I'll have to find a bigger bucket to do a destructive test.
