Simple Shelf Bracket (many sizes)

thingiverse

By the past I acquired that simple shelf brackets which hold a shelf solely by its own weight. Unfortunately, I couldn't locate it anymore in my neighborhood. So I decided to create my own, and make it parametric, so I can adapt it to any shelf thickness. So if you like a custom bracket to match your board thickness, feel free to ask. Please note that kind of brackets are not heavy-duty. If you want to hold a heavy shelf, multiply the number of brackets. In the same way, use the proper screw according to the weight each should hold. If you're not confident, make some tests. Print Settings Printer Brand: RepRap Printer: Prusa I3, CoreXY Rafts: No Supports: No Resolution: Does not matter Infill: The higher, the better Notes: Please note that the best strength is achieved with the bracket printed close to the bed. This way the layers are perpendicular to the shelf. Print at the highest temperature the filament can hold, to prevent delamination. Please note The infill percentage matters for the bracket's strength. Adapt the infill to the weight the shelf is meant to hold. As the strength of the brackets depends a lot on the settings and printer which make it, if you're not confident, or in dangerous configurations, do some testing before permanent use. Here (and here only, my printer, my plastic, my shelf, etc.), a pair of 100% infill 18mm bracket holds a 1000x200mm shelf supporting 4x10kg containers, with 8mm wall plugs and 6x60mm screws. I guess It can hold more but I haven't tried yet. A single 5mm bracket holds a 300x100mm glass shelf with 5 full-size perfume bottles, with 5mm wall plug and 2.5x30mm screw. Post-Printing Please note... The shelf is not meant to reach the wall. If you want it, cut a recess corresponding to each bracket's thickness.
