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...

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...

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...

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...

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...

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...

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...

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...

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...

I got various requests and great ideas from you about how to improve the storage boxes system. Thank you very much for all the great ideas and suggestions! 😄 One request I got many times was storage boxes with a...

The regular storage boxes set got an update today. All existing boxes are now available in a new revision with an improved corner design and there are four new boxes in the set. The title image shows all current boxes...

I created a version of my storage box for 45º belt printing. It would be ideal for mass production. Because I do not own a belt printer, this design is a wild guess. If you own one, I invite you...

I added a fan and temperature controller to my printer enclosure with this quick 4h build. You may need to adjust things a little bit, but I am sure you can build one for yourself in less than a day....

I just updated the flat boxes set. All existing boxes got a new revision, with an even better wall profile and there are five additional boxes in this set. Improved Wall Profile If you compare the corner for revision A...

The tall boxes set is ready for download, after successfully completing my tests. You will get carefully designed storage boxes, optimised for 3d print from the ground up. Only this weekend, from 2020-11-27 to 2020-11-29, all STL files in the...

Finally, my tests of the flat storage box are finished. 🎉 The main issue I had, was the spot for the labels. With the geometry I used in the regular and tall boxes, it took too much space from the...

One of the reasons I didn’t publish as many articles are before, is I am still organising my new lab. Because of the current pandemic, everything got delayed and there is still a lot of material which needs to be...

I wrote a small application to generate random circle patterns. You just specify the width and height of the rectangle to fill and the application will fill the area with the circles you specified. The result can be exported in...

Today, something slightly off-topic. This post is a short tutorial on how to build a heavy and solid 3D-printer enclosure. It uses a fully parametric design, where you can adjust the important dimensions – therefore it should work with a...

Recently I published a simplified version of the Always-On project hardware. Read this post for details. Today I publish a firmware example for the Always-On project. This firmware is written for the PlatformIO environment using Visual Studio Code. It is...

In most of my last projects, I used nice miniature connectors from TE. This is, again, no sponsored post. If you ever evaluated connectors, you may know how overwhelming the range of products is. I like to introduce these connectors...

I received new boards from PCBWay for the Always-On project. They are well made for a really low price. As you can see in the previous image, the layer alignment is very good. Also, I do not have to worry...

First, this is no sponsored post. I like to put my devices into a nice case. It does not only look more professional, but it also protects the electronics from dust and water. If you ever searched for a nice...

I just finished a new project, which is called Always-On. This project is a simple bidirectional bridge between the mains-voltage installation and an Adafruit Feather board as a controller. The idea is to have a device integrated into the electric...

Today the stencils from OSH Stencils arrived for the Swiss precision timer project. I used to work with steel stencils for all my previous projects, therefore the polyimide film (3mil) ones feel very flimsy to me. I will see how...
