Description
This tube is intended to be boltet down in front of a nesting boxes entrance hole.
It prevents predators, like feral cats or raccoons, from just reaching into the box to feast on the birds. This is especially importand at low hanging boxes, boxes and houses on poles or if there are any branches near the box
The protector has slots on its circumference to make it appealing for birds to go trough.
CHANGE LOG 21.01.2023:
Added a “Robust” version with even thicker walls and a reinforced flange area. The tubes outer diameter is now 50mm
CHANGE LOG 01.10.2022:
The inner diameter is changed from 45mm to 44mm in order to make the walls slightly stronger.
credit where credit is due:
I got inspired by a similar tube https://www.printables.com/de/model/140027-predator-protection but had some issues printing it at verry high speeds due to the circular shaped holes. So i came up with my design
