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've designed a simple magnetic filament filter that snaps onto a 16mm feed-through to catch dust and particles with a microfiber-wrapped sponge. It's easy to attach, low-friction, and printable in PETG — STL and Fusion360 files are included. Read the full post for printing, assembly and download links.

I designed an experimental storage box for 45° belt printing and shared the STL for others to try. I haven't printed it myself, so it's a best-guess layout optimized for 0.2mm layer height and common nozzles. If you have a belt printer, please test it and tell me how it performs, and read on for details.

I've finished testing a flat storage box set for 3D printing and adjusted the label profile so they stack neatly with regular boxes. I designed them to save drawer space for rarely used parts. Read the full post for stacking details, label geometry, print settings, and download links if you'd like to try them.

I’ve published a simple firmware example for the Always-On project, built for PlatformIO and Visual Studio Code with my HAL adapted for Adafruit Feather M0. It explains the hardware mapping, motion-triggered lighting behavior, and timing options. Please read the full post for setup instructions and the GitHub link.
