Tay đỡ kệ bánh răng (Gear shelf bracket)

I built a large static display model train and wanted a shelf bracket that would match.  It needed to be strong and while I liked many of the existing gear brackets, none of them seemed quite right. Using TinkerCAD, I leveraged their Shape Generator for the gears and then put in some holes for screwdriver access.

Printed in black PLA, with 25% honeycomb infill and they seem very strong!
