Stable bird feeder platform 120mm/20mm (Mouse climbing protection)
thingiverse
Another platform I use as a bird feeder but also protection against climbing mice. Diameter is 120mm for a 20mm rod. If your rod has a smaller diameter, just make a simple adapter ring to fit it. There are two holes for M4 screws to fix the platform. You have to cut the threads yourself. I used 20% infill on the platform and 80% infill in the rod housing.
