This project provides a 3D printable fat ball feeder for small birds. The design includes a feeder for holding one ball and another bigger feeder for two balls.

Note: This project is GPLv3 open-source. The github repository for the model (containing the complete OpenSCAD project) can be found at https://github.com/simoninns/fat-ball-bird-feeder

The model has been printed and tested on the Prusa MK3S/MMU2S printer using PETG filament. All parts fit on a 20x20 printing bed.

• Material: PETG
• Layer: 0.20mm (Quality)
• Infill: 15%
• Supports: No Supports

Screw the lid onto the feeder body. The lid might be a little stiff the first few tries; simply screw the lid on and off a couple of times to smooth out the plastic.
