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…
Round Corner Template Set for Woodworking
Sometimes I like to have rounded corners in my woodworking projects. It seems many people like to soften the spiky ends of their panels because there is a huge range of templates for routing. If you own a 3d printer, it is handy you can print just the template with the size you actually need….
Adafruit PowerBoost 1000C Enclosure (LR2165)
I made a simple 3d printed enclosure for Adafruit’s PowerBoost 1000C and a 1200mAh or smaller LiPo battery. This post contains all the files you need for the print, a list of components, and assembly instructions. My design uses three simple parts with tight tolerances. They are held together with two M3 screws and two…
New Storage Boxes
Today I published several new storage boxes with the label section placed at a different side. So, it will allow you to use the same box size in a drawer but keep all label orientations the same. The following two illustrations show the difference between the 1✕2 and 2✕1 size: Both boxes have exactly the…
Split Storage Boxes Update
I got many requests to add split storage boxes to my system. Reasons were to print huge boxes and printing boxes on small printer beds. In the past few days, I released an update to my storage boxes system, introducing the first split boxes. If you bought the storage boxes set from my shop, you…
Comparing Five Turntable Platform Revisions
To solve the problem with light inference, I tested five different revisions of the turntable platform. For each revision, I recorded the sensor values and compared them to find the best solution. Visual Comparison Revision A is the original with the light inference problem. In the text, I describe only the differences to this original…
Let’s Print a Cat/Pet Feeding Device (Part 7)
The seventh part of this series is all about the sensor board. It hosts the position sensor and four fill sensors. Speaking of sensors sounds complex, but these are just pairs of IR-LEDs and phototransistors. All design files for the board are in the GitHub repository and if you missed one of the previous parts,…
Adding a Light Barrier using Epoxy
As you read in my last post about the pet-feeding device project, there was an issue with the fill sensors. The lines from the 3d-print transferred the light directly to the sensor and made a useful measurement impossible. One of the solution to this problem is a small gap between the LED and the sensor….
Unexpected Fill Sensor Problems
While testing the sensor panel, I ran into unexpected problems, requiring a small redesign. First, let me explain the simple working principle of the fill sensor circuit and what I tested so far. The Circuit The circuit for the fill sensors is straight forward. There are four input lines and one analogue output line. If…
