-Added the Auger screw STL Itself, cause the original design seems to be gone of thingaverse from the original designer. Otherwise this design is worthless!
-Added more information on what components i used and electronics to control it.

Stepper motor adapter for Auger for 50MM PVC tube fitting

This part is a remix of the original of the designer who made : thing:27854/
I repurposed it to use as a auger for my chicken feeder.

in Holland we have grey 50MM PVC tubing (The T Part). That is almost the same size "Almost" as used in the original design. The diameter is a bit bigger, so i enlarged the fitting fingers on the stepper adapter to make a screw hole after printing on both sides or to glue it, but that is to permanent for maintanence i discovered. When you simply screw it, you can fix issue's aftrerwards without much fidling.

Also i designed a mounting plate for 50MM PVC tubing to mount the PVC T-part under my barrel as a mini silo on a hightened wooden mount as seen in the photo. This works as a charm.

As the driver for the stepper motor i used a Adafruit motorshield V2:

(I used the china version of a few euro :P ) < Also works

As the controller for the driver shield i used a Wemos D1 R2. This is the same form factor as the driver shield, so you do not have to modify the driver shield (You have to mod it for the voltage otherwise).

This combination makes a wonderfull wireless controller node for the stepper motor!

Casing for the driver shield, together with the controller:

This case is easy printing and easy installing!

For the Controller i used the software: ESPEASY:

(The function for the Adafruit motor shield V2 is still in testing, so when you choose the firmware to upload to the ESP8266 Controller shield "Wemos D1 R2" please choose the "DEV" version. This should be somewhere on the bottom of the list of firmware versions in the list when you download the latest version. This ESPEASY is the easyest thin i used today to flash a ESP8266. There comes a tooling to make i even more easyer.

For this you need some sort of controll server like what i use: Domoticz

This runs of a Raspberry PI and can controll al sort of IOT stuff. You can put thins tiny server everywhere, as long as your Access point is near the Controller for WiFi Range.
