Picked up a Mastercraft Work Table (399-1300-2) for an inkjet printer. Decided it needed an additional shelf, so made up these brackets to support a shelf. Shelf (not shown) is 3/4" pine jointed board cut to fit.

Brackets secured to legs with #8 x 3/4" self drilling metal screws.Used #8 x 1" pan head metal screws to secure the shelf down to the brackets.

Printed in PETG. 25% infill, 5 layers top/bottom/sides. You will need two of each bracket.
