I just published another set of 500 boxes. The new set has smiley faces as decorations. As with the heart and lines set, the box comes in 500 sizes with two different lids for each. Part Numbering To choose the right box, you need to know the inner dimensions. There is the width (x), depth…
Box with Random Line Pattern
Because the box with the heart pattern worked out great, I tried something more complex this time. The new set features a random line pattern. All four sides of a box have the same, but each box has its own random pattern. Like the previous set, I generated 500 different sizes for the box with…
Let’s Print a Cat/Pet Feeding Device (Part 3)
In this third part of the series, we print three panels for the enclosure and the rotary platform. If you missed the first or second part, visit the overview page to access them. The Files You will find all required files for the following prints in the GitHub repository: The Left Side File: LR2051-404A.stl Material: PETG…
Box with Heart in 500 Sizes
I tried something new with parametric design. 😄 Today I publish the first batch of heart decorated boxes for 3D-print in 500 different sizes. The sizes start from 35mm up to 120mm in small steps, so you can choose a box in the perfect size for you. The print above is a very small one,…
Let’s Print a Cat/Pet Feeding Device (Part 2)
In this part, we assemble the gearbox. It is the second part of this series. If you missed the first one, read it here. Requirements for this Part You will need the printed objects from the previous post: LR2051-101B.stl LR2051-102B.stl LR2051-103B.stl LR2051-104B.stl LR2051-105B.stl LR2051-107B.stl LR2051-108B.stl LR2051-111B.stl LR2051-112B.stl LR2051-121.stl LR2051-122.stl LR2051-123.stl LR2051-124.stl LR2051-401A.stl Also, these components:…
Electronics Invisibly Embedded in 3D Prints
After successfully embedding magnets, I started experimenting embedding whole PCB boards into prints. I am sure, this is no new idea, but I found it very interesting. From the outside, the printed object looks solid and there is no trace of the board visible. The board and all electronics are perfectly sealed in the part….
Let’s Print a Cat/Pet Feeding Device (Part 1)
Do you own a 3D printer and would like to start a complex and challenging project? Then let’s print a fully functional, programmable cat or pet feeding device! 😄 In this multi-part series, I will guide you step by step through the printing and assembly process of all mechanical parts. I will also provide PCB…
Yet Another Filament Filter
I had several times problems with a clogged nozzle, and recently found particles on new filament spools, which could have to be the reason for it. So I checked different filter solutions, but found no one fitting perfectly into my setup. My Design Goals Easy to attach and remove after each spool change. On top…
“Read SGP30” Command-Line Tool
I published another small command-line tool for Raspberry-Pi. This time one to read data from the Sensirion SGP30 sensor. While you can communicate over I2C with sensors using Python, I found it not as reliable as using compiled C or C++ programs. To combine the two worlds, I started writing really small command-line tools, which…
“Read SHT31” Command-Line Tool
For various sensors, attached to Raspberry-Pi computers, I wrote small command-line tools to read the sensor values over the I2C connection. While you can do this with a Python script directly, I found using a compiled C or C++ program accessing the low-level device more reliable. The program I publish today, reads temperature and humidity…
