In Part 3 I print three enclosure panels and the rotary turntable for my 3D-printed cat/pet feeder. I share the STL files, PETG print settings, and notes on warping and difficulty. If you're following the series or planning your own print, read the full post for detailed tips and links to the turntable guide.

I built a 3D-printed cat/pet feeder and documented every step across seven posts: printing the gearbox, assembling parts, crafting the enclosure, and adding electronics and a sensor board. If you want to follow the process or reproduce the device, read the full build series for parts, tips, and notes.

I'll walk you step-by-step through printing the mechanical parts of a fully functional, programmable cat/pet feeder. I share STL files, material and printer recommendations, and parts lists — all open-source on GitHub. If you have a 3D printer and want a challenging build, read the full post to get started.

I recently finished a compact cat feeder and made small upgrades — I added a USB charging port and a larger battery so it can run for months. I put together a short demo video and linked the project notes; if you’re curious, please watch the clip and read the full write-up.

I built a simple, single-portion programmable cat feeder in about four days using rapid prototyping. I describe the Fusion360 sizing, plywood shell, servo mechanism, electronics, and the issues I encountered with breakout boards. If you're curious, read the full post for parts list, wiring and source code.
