Let’s Print a Cat/Pet Feeding Device (Part 3)

In this third part of the series, we print three panels for the enclosure and the rotary platform. If you missed the first or second part, visit the overview page to access them.

The Turntable Platform

This is the most difficult print of the project. After some problems with the initial design, I wrote a separated post how to print this part:

Conclusion

This is the end of the third part. In the next part we will talk about the enclosure panels in the front and back of the device. While all of the previous prints were universal, you might want to do changes on them – depending on the components you want to use.
