These brackets were designed to make a spice rack with 10mm dowel rods, but because it's about double the width of a normal spice rack it can also be used to make a lightweight storage shelf.
There are three parts to the model - the outer brackets (left and right side) plus a middle bracket to support a longer shelf lenth if desired.
A single shelf needs four 10mm dowel rods of whatever length you require. The dowel rods simply slide into the holes with a fairly loose fit and don't need to be glued into the end brackets unless you want a sturdier shelf.
I printed these in PLA with a 0.4mm nozzle, 0.2mm layer height and 15% infill and they seem pretty strong.
I had some issues with bed adhesion so a brim is recommended.
I hope you find this useful, happy printing :-)
