Dog Food Dispenser

## Dog Food Dispenser! Made to fit onto a 4 inch diameter (inner diameter) PVC Tube. I used a 3ft tube but could be longer or shorter. ### Printing I used PLA, with a 0.6 Nozzle. Worked great, Is strong enough so far. ### Parts: PVC was found here: https://www.etsy.com/listing/721456729/clear-pvc-pipe-choose-your-length-5 Let me know if you find a cheaper source for 4 inch PVC. Requires 5-10 ~16mm M4 Screws with washers, but there is flexibility here with screw size and length. M3.5 - M5 would probably work. In addition a ~53mm M4 bolt and nut is required for the cup axle. I have the one I used pictured. Let me know if you know how to properly notate this bolt. It has a 47mm "grip" length and 6mm thread length. #### My Part list: - 4" ID 4.5" OD PVC Pipe - 5 M4 Screws (w/ washers) - 53mm M4 bolt - M4 washer #### Tools: - ~3.5mm drill bit (just smaller than a M4 bolt) - ~4.5mm drill bit (just bigger than an M4 bolt) - 1/2 inch drill bit - Drill / screwdriver ### Assembling Assembling is simple, given you have a drill and the required bolts. 1. Insert in the middle funnel 4-6 inches from the bottom. Drill 3.5mm holes on at least two of the sides and drill in M4 Bolts to hold it in place. 2. Insert the Cup into the bottom and rotate it to get a good idea for where it should be. Too close to the funnel and it will scrape it, and too far will let kibble fall through and get stuck. 1.75 inches was the sweet spot for me. 3. Drill a 4.5mm hole on one side of the pipe for the 53mm bolt, and a 0.5 inch hole on the other side for the shaft. 4. Fix the knob to the handle with an M4 bolt. 5. Insert a M4 Nut into the slot at the end of the shaft. 6. Hold the cup in place, and insert the shaft into one end, and the bolt on the other end. Tighten the 53mm bolt until there is not much wiggle room, but still freely rotates. 7. Slide 1-2 brackets onto the tube. For me the fit was tight enough that I did not need screws. but screw holes are on the bracket for better holding. 8. Pop on the top cap and bottom funnel, optionally fix it with a bolt. 9. Mount to a wall 10. Enjoy!
