120 degree brackets

My wife wanted some hexagon shelves but getting the angle right and holding it in place for the glue to dry was a pain. These simple brackets helped a ton. 15mm wide (made for ¾" boards) with 2x countersunk holes for M4 (or #4) screws. Printed with 3x wall layers and honeycomb infill at 20%, but honestly you could just do default and be fine.
