I recently built a relatively large (100cm × 80cm) 3D printed artwork, which features a painted relief of mathematical functions. Read how I prepared the data, converted it into 3D printable tiles and converted them into printable gcode. All the images and previews are from the proof of concept I created. The final artwork is…
Huge Storage Boxes Update
Today I release a huge update of my storage boxes system for 3d-print. This update not only further improves the geometries of the models, but also extend the available sizes and variants. There are now 1000+ model files in the full set you can buy in the shop. As a buyer of one of the…

The following two illustrations show the difference between the 1✕2 and 2✕1 size: Both boxes have exactly the…
Build and Heat Treatment of a Carbohydrate Source
In this short tutorial, I will explain step by step, how you can build a solid carbohydrate source. You will find the bill of materials and all required tools. I will use SI units to simplify all measurements. This is no quick build, the substances require long reaction and activation times. For this reason, the…
Logic Gates Puzzle 100
Assume, while digging out an ancient site from 450 AD, you found a mysterious stone with a digital display. Your analysis finds five inputs for five segments (a–e) and six outputs (1–6). It seems to be a classic multiplexed display. What is this display for? What is the highest continuous sequence of numbers it can…
Logic Gates Puzzle 11
The shown logic circuit performs a well known function; can you discover what it is? The circuit was not optimised for functionality, but to create a symmetric artwork. If you need to know the meaning of the used logic gate symbols, have a look at this Wikipedia page. Also, there are great videos from Ben…
