I walked through designing and 3D-printing a 70 cm PETG planter for my deep-rooted Ctenanthe. I share the tests, design choices, and practical fixes for warping, filament, split parts, and assembly. If you’re curious about large-scale prints or want the model files and tips, please read the full post.

I'm pleased to share the 2024 revision D of my 3D-printed storage boxes. After extensive testing and fixes—from rail-grid grooves to label-area ribs—I updated geometries, added dividers and 3MF/STEP files, and released hundreds of free models. Read the full post for details and download links.

I've created a collection of 3D-printable flower pots—geometric, Roman-vase inspired, striped and spiral—optimized for practical printing on machines like the Prusa XL. I share lessons on wall thickness, corner radii, nozzle sizes and model files. Read on for design details and downloads.

I've added a batch of new divider layouts across my storage box system — regular, flat, tall, triple and extended series — based on your feedback. I've updated documentation and uploads; downloads are available on the new platform. Please take a look and read the full post for details and download links.

I've released Pattern Generator v2.0.4 with a rewritten 64-bit fixed-point backend, a new shape browser, extra placement algorithms, adjustable canvas shapes, faster style previews and improved file handling. It's free for macOS and Windows — read the full post to see examples, download links and details.

I'm not a 3D‑printing expert, but I show how simple wall profiles — correct XY/Z thickness, chamfers, and internal recesses — make printed boxes stronger and lighter. I share CAD steps, simulations, and common mistakes in plain terms. Read the full post for practical tips to improve your prints.

I'm not a 3D printing guru, but I built and tested three print-in-place hinges optimized for PETG/ASA and explain the small design choices that make them work reliably. I walk you through bridging, fin widths, overhangs, and conical holes — read the full post to learn how to print them well.

I explain why I add small guide bridges to tricky gaps in my 3D prints and how they help PETG bridging. I show the settings I use and demonstrate results in my modular lantern model. Read the full post to see images and step-by-step tips to apply this to your designs.

I tested a simple technique to strengthen FFF prints by adding a zig-zag vertical link between the outer and inner perimeter. My demo gcode and findings show how peaks fuse layers and slow crack propagation. If you print regularly, read the full post to see my method and limitations.

I created a logic-gate puzzle featuring a gated D latch: more artwork than optimized circuitry. I invite you to try decoding the hidden message—there are hints and links to gate and flip-flop basics in the post. I hope you enjoy the challenge; read the full article if you'd like to solve it.

I explain microcontroller firmware that emulates candlelight using layered, low-resource random waves and simple integer math. I cover color gradients, LED mapping (WS2812B), and flicker modulation so constrained boards can produce organic light. If this interests you, please read the full post for code and details.

I tested three inexpensive, easy methods to add LED lighting to my modular 3D‑printed lantern using USB power: reused LED modules, short 5V strips, and WS2812B RGB with a microcontroller. I share parts lists, soldering tips, diffuser advice, and firmware steps—read on for step‑by‑step instructions and printable models.

I designed a modular 19th‑century‑style lantern you can 3D print as a candlelight or expand into an LED street‑lamp stand. Read on for my glue‑free assembly, colour‑layer printing tips, and stand options — or jump to the Printables page for downloads and print instructions.

I published a detailed update to my stackable storage boxes project that adds new rail grid series, larger sizes up to 9×9, and improved catalogues. I outline design reasoning, alternative part-number placement, image and archive changes. If this sounds useful, please read the full post for downloads and printing notes.

I show how I built a refillable replacement for the Philips FY3432 active coal filter using 3D‑printed PLA parts, mesh, M3 insets and epoxy. If you want a lower‑waste workshop air filter and practical assembly steps, read the full guide — I cover materials, print files and tips.
Posted on 2022-09-04— C++, Improve your Code, Learn
I take you on a short, pragmatic journey into C++ integer pitfalls—why signed and unsigned types behave oddly, how literals, negation and overflow can bite, and simple tests to reveal compiler quirks. If you work in embedded or systems code, please read the full post for examples and guidance.

I built a 100×80cm 3D‑printed artwork and walk through the technical steps I used: preparing mathematical height data, generating Z‑maps, slicing into printable tiles with Blender and PrusaSlicer, and assembling and painting the final piece. If you're curious about the scripts and workflow, read the full tutorial.
