Simple Shelf Bracket (many sizes)

By the past I bought that easy shelf brackets that hold a shelf by it's own weight. Unfortunately, I could not find it anymore in the neighbourhood. So I decided to make my own, and make it parametric, so I'm able to adapt it to any shelf thickness. So if you like a custom bracket to match your board thickness, feel free to ask. /!\ Please not 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 the best strenght is achieve with the bracket printed the chick on 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 mat
