This feeder was designed to be an improvement on similar store bought options. It provides more room, can closely match the feed containers profile, and includes a hump to reduce waste.
Measure your feed containers diameter in millimeters and download the pair of profiles that is closest to your measurement. I found it doesn't have to be a perfect match to still be a good fit.
The design can only support “5 gallon” buckets and larger, or flat sided containers.
Settings I used with a .4mm nozzle:
- 3 perimeters
- .45mm extrusion width
- .2mm layer height
- Seam position: Rear
- The seams work as a guide to help install it perfectly vertical, and prevents them from being on the main opening keeping it smoother.
- No supports.
- PLA has worked fine for me. One revision of this feeder has been in use outside for a year and still looks new.
The threads are fine, so your printer will have to be performing well. If it is still tight, try a light sanding to knock down any rough spots on the threads, a bit of lubricant, or try reducing the extrusion multiplier on the lock ring by a couple percent.
To assemble, simply print the main body, lock ring, and a pair of profiles that closely match your container's diameter. Sand any rough spots that the chickens will be in contact with!
- Utilize the exterior profile as a cutting template for the hole. There are notches to help align it. Trace along the inside of the ring, and cut on, or just outside the circle you drew.
- Screw the interior profile on the body, and insert the feeder from the inside.
- Slide the exterior profile into place, and secure it with the lock ring.
Here are diameters I measured from some common USA farm store containers:
| 5 Gallon Bucket | 255mm dia |
| 10 Gallon Galv. Can | 342mm dia |
| 20 Gallon Galv. Can | 395mm dia |
| 32 Gallon Poly Can | 455mm dia |
If you want a perfect match to your container, I included the FreeCAD files. Type your diameter and wall thickness in the spreadsheet in the green cells to quickly change the model.
