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 built a PID-controlled fan and temperature controller for my printer enclosure in about four hours using an Adafruit Feather, DHT22, OLED, MOSFET, and a PWM fan. I walk through printing the case, wiring, firmware setup, and assembly—read on if you'd like to build one yourself.

I've updated the flat boxes set with a refined wall profile (revision B) and added five new boxes, including a large 2×4 and four grid variants. I show corner comparisons and note existing customers received files. If this is useful, please check the full project details on the project page.

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 been reorganising my lab and designed stackable organiser boxes optimised for fast 3D printing. They use a 60×60mm raster, stabilising walls, dual label slots and rail grids. I offer a free STL subset and explain print settings—read the full post for downloads and the complete shop set.

I’ll walk you through my parametric, heavy wood-and-acrylic 3D-printer enclosure — from choosing boards and adjusting the Fusion 360 model to cutting parts, assembly, and 3D-printed hinges. If you want a stable, customizable enclosure for your printer, read the full tutorial for measurements, photos, and tips.

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.

I often reach for TE's Micro‑MaTch connectors when I need compact, hand‑solderable board-to-board connections. They saved me routing space and allowed SMD pads on tiny sensor boards. I share my requirements, examples, and practical tips — please read on if you're choosing connectors for small projects.

I recently built 'Always-On', a minimal bidirectional mains-to-Feather bridge combining a power sensor and solid-state relay for safe home-control prototypes. I outline design choices, safe firmware testing without mains, and housing tips. If you're exploring a similar controller, read the full post for a practical starting point.

I received 3mil polyimide stencils from OSH Stencils for my Swiss precision timer project. They feel flimsy compared to the steel stencils I usually use, but cost much less. I’ll test solder paste application and the first prototype in the coming weeks — please read the full post for results.

I’m building a small utility called the Swiss-Precision Timer and just received prototype 37x18mm two-layer boards from PCBWay. They’re populated with tiny SMD parts I plan to reflow using a stencil. The project is still a prototype — I’ll share assembly notes and updates once I solder the first version. Please read on.
