Bird feeder (Easy clean, easy refill)

This bird feeder is designed for installation on a wooden rail, the top of a wooden post or on a wall.
The model has a dovetail mounting plate for easy removal.
 

Model parts: Main box, Roof, Locking pin, Standard plate and Wall plate.
 

The interior of the feeder has been designed to limit sharp corners where seeds accumulate.

The base of the feeder has water drainage channels. 

Installation
The standard mounting plate is for post or rail mounting, the wall mounting plate extends past the roof rear overhang.
The benefit of the Standard wall plate is it uses less filament. Only one mounting plate is required to install the bird feeder.

The roof of the feeder is slightly angled and has a recess underneath for the main box. The roof also has a large overhang and contains drip channels to limit rain ingress. To install the roof, you should hook the roof onto the main body (at the front) and lower the roof at the rear, installing the pin at the rear of the feeder. 

The suggested filament for this model is PETG, PLA can be used, but it will degrade over time.  The model was printed with both filaments, so that I can test longevity.

This model was designed in Plasticity.
