In this post, I write about wall profiles in 3D printing, and I will explain why they are essential to creating stable parts with minimal filament use. Also, I will show common mistakes that result in ugly prints and discuss this topic by designing a simple 3D-printed box. Preface I am no 3D printing expert,…
The Hinges and its Secrets for Perfect PETG Print
A while ago, I published the models for three different strengths of print-in-place hinges. If these are printed with PETG or ASA, they are incredibly strong and durable. This post explains why these objects print so well with challenging materials. Preface I am no 3D printing expert, and the topics I discuss here are nothing…
Better Bridging with Slicer Guides
I got questions about a particular feature you find if some of my 3D models. In this short text, I will explain why I add it and why you should add features like this too. How the Features Look Like Please check out my latest modular lantern design if you want to see the technique…
Stronger 3D Printed Parts with Vertical Perimeter Linking
One issue with fused filament fabrication is the weakness introduced into the parts at the layer boundaries. I had this simple idea of how especially straight sections of 3D prints could be improved on regular printers. Now I found time to test my idea. Linking Two Layers at the Perimeter The principle is simple. A…
Logic Gates Puzzle 101
The message you got does not make any sense. Can you decypher it with the following logic puzzle? The circuit was not optimised for functionality but to create a challenging puzzle and gorgeous artwork. If you need to know logic gate symbols’ meaning, look at this Wikipedia page. This puzzle features a gated D latch. If…
Candlelight Emulation – Complexity with Layering
In this blog post I explain the microcontroller firmware that emulates candlelight in more detail. You can apply the explained techniques in similar situations to get organic effects on CPU and RAM-limited platforms. I will focus in my description on emulating a convincing random effects with minimal resource usage. Demo The following video demonstrates the…
Three Ways to Integrate LED Light Into the Modular Lantern
After creating the modular lantern system, I experimented with different cheap ways to integrate LED lights into it and turn it into a decorative lamp. In this post, I describe the three ways I found the cheapest and easiest to implement that all create a wonderful result. Preface When I set up real light installations,…
The 3D Printed Modular Lantern
I designed a very modular 19th-century-style lantern. You can print it in its simplest form as a simple candlelight to put on a table or a shelf. By printing additional elements, you create a wonderful LED lantern with a stand that looks slightly like a street lamp. In this post, I share details about my…
Rail Grid Alternatives and More Interesting Updates
I published another large update to the storage boxes project in the last two weeks. All buyers who subscribed to update emails already got a summary of the changes. If you read the email, you can skip this post unless you are interested in even more detail. The new and updated models are downloadable from…
Large Update to the Circle Pattern Generator
Today I published a significant update to the circle pattern generator. Version 1.4.1 of the application is available for macOS and Windows for download. This new version adds various shapes, rotations, colours and a generator for circular or elliptical canvases. Shapes Circles are great, but different shapes may be better. The new version contains a…
