Summary

My bird houses have tripods to rest on. Unfortunately the slope of the legs of the tripod is not steep enough to hinder rodents climbing up and steeling the birds food...

Initial design of a rodent barrier was a plate placed around each leg of the tripod.
I started with a central hole in the plate for the leg.
Some iterations led to excentric holes to provide more barrier at the "rodent runway" (i.e. upper) side of the leg.

The sleeve around the leg has some 5mm bore holes for mounting.
The sleeves are designed for legs with a cross-section of about 33 x 40 mm.
Of course you need to print two identical parts of those half-plates and combine them to a whole plate.
This thing has a diameter of 31cm.
