Need some hardware for your wire shelf and want to skip a trip to the hardware store? I know I did. Look no further - now print your own, heavy duty shelf bracket to replace those flimsy store-bought ones that broke because you overloaded the beans out of your wire shelf with your ever growing collection of filament.

Highly recommend printing on the edge of the bracket. The slicer's automatic placement function may try to put the bracket flat-side down, but that puts the stress on the Z-axis and the bracket may break along the layers (don't ask how I know). 

Easy and cheap to print (about 10-15 min for 2 brackets). PTA and PETG work just fine but if you have ABS that would probably be even better for load bearing.
