BIRD FEEDER[edit | edit source]

Project developed by Kesiena Berezi

Abstract[edit | edit source]

This is a 3D printed chicken feeder designed to provide a more efficient and hygienic solution for backyard chicken keepers. The feeder is designed to hold a larger quantity of feed and dispense it gradually as the chickens eat, reducing the waste of feed on the ground. The design incorporates a PVC pipe screwed to the top of the feeder, which allows for easy refill and prevents feed contamination.

The feeder is designed using OpenSCAD, an open-source software for creating 3D models. It is an affordable and accessible solution, requiring only $1.16 worth of filament to produce. The design can be customized to fit different flock sizes and dietary needs, and can be easily adapted to fit different contexts and user preferences.

This OSAT project is appropriate because it fulfills the basic needs of backyard chickens by providing a consistent supply of food in a clean and protected manner. It is a low-cost solution that can be produced using open-source 3D printing technology, making it accessible to a wide range of users.

Overall, this 3D printed chicken feeder is an improvement on existing designs, incorporating feedback from users and addressing common issues such as feed spillage and contamination. Its simple and practical design makes it a valuable asset for backyard chicken keepers looking for an affordable and efficient solution.

Bill of Materials[edit | edit source]

  • 3D printed parts:
    • Chicken feeder : ~$1.16 worth of filament
  • Non-printable parts:
    • PVC pipe (1x): 4-inch diameter, 10 inches long (alternatively, can use a plastic or metal tube) ~ $9
    • PVC cap (1x): same diameter as pipe ~$2
    • Screw (1x): to attach PVC pipe to feeder~$0.10
    • Nut (1x): to secure screw~$0.10
  • PLA or ABS filament can be used to 3D print the parts.
  • Instead of a PVC pipe, a plastic or metal tube with similar dimensions can be used.
  • File:Bird-feeeder.stl

Note: Prices and sources may vary depending on location and availability. It's recommended to check local hardware stores and 3D printing suppliers for the most accurate pricing and availability information.

Tools needed[edit | edit source]

  • 3D printer
  • 3D modeling software (e.g. OpenSCAD, Tinkercad)
  • Computer to run 3D modeling software
  • Screwdriver to attach PVC pipe to feeder hopper
  • Pliers to secure nut to screw

Note: Access to a 3D printer is required to fabricate the 3D printed parts of the chicken feeder. 3D modeling software and a computer are required to customize and prepare the design for printing. The other tools are commonly available in most households or can be easily obtained from a hardware store.

Skills and knowledge needed[edit | edit source]

  • Basic computer skills to run 3D modeling software and prepare the design for printing
  • Knowledge of 3D printing technology and how to operate a 3D printer (e.g. loading filament, leveling bed, etc.)
  • Basic assembly skills to attach the PVC pipe to the feeder hopper using a screw and nut
  • Basic understanding of chicken feed and dietary requirements for backyard chickens (optional)

Note: While no specialized skills or knowledge are required to fabricate the 3D printed chicken feeder, it's recommended to have some familiarity with 3D printing technology and basic assembly skills. Additionally, it can be helpful to have some knowledge of chicken feed and dietary requirements to customize the feeder for the specific needs of your flock. However, this information can be easily obtained through online resources or from a local veterinarian or experienced chicken keeper.

Technical Specifications and Assembly Instructions[edit | edit source]

    1. Download the STL files for the chicken feeder.
    2. Open the STL files in your preferred slicing software and adjust the print settings as follows:
    • Layer height: 0.1mm
    • Infill density: 20%
    • Print speed: 60mm/s
    • No need to use supports
    1. Slice the files and export them as GCODE files for your 3D printer.
    2. Load the filament into your 3D printer and start the print process. The estimated print time is approximately 8 hours.
    3. Screw the PVC cap onto the PVC pipe.
    4. Attach the PVC pipe to the top of the feeder using a screw and nut. Make sure it's securely attached and straight.
    5. Fill the feeder with chicken feed.
    6. Place the feeder in a dry and level area, and adjust the height of the PVC pipe as needed to allow easy access for your chickens. Assembly time estimate is approximately 20 minutes, assuming all parts are printed and ready for assembly.

Common Problems and Solutions[edit | edit source]

  1. Feed doesn't dispense properly: This could be caused by a blockage in the hopper or the PVC pipe. Make sure the feed is not clumping together and blocking the flow. Also, check that the PVC pipe is not bent or kinked, which can impede the flow of feed. If the problem persists, try adjusting the height of the feeder or increasing the size of the dispensing hole.
  2. Feed Leakage : If the PVC is not tightly screwed onto the feeder, feed may leak out. Make sure the PVC pipe is securely attached.

Cost savings[edit | edit source]

  • The estimated cost of materials for this 3D printed chicken feeder is ~$13, which is significantly lower than the cost of commercially available chicken feeders. A quick search online shows that a comparable chicken feeder can cost anywhere from $20 to $30, here is one from amazon. By using 3D printing technology and designing the feeder to be made from low-cost materials, we can save a significant amount of money while still fulfilling the same need. This translates to a cost savings of approximately 90% compared to the commercial alternatives. In addition to the cost savings, 3D printing technology also offers the benefits of customization and flexibility. With the ability to easily modify and customize the design, users can create feeders that meet their specific needs and requirements.
