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…
Fusion 360 Storage Boxes Insert Template
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 flat bottom. The reason for this was to have a straight surface to store objects…

Storage Box for 45º Belt Printer?
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 to test this design. The box has to be printed sideways, the shorter side in…
Quick 4h Build – PID Fan Controller
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. Used Material Adafruit Feather M0 Proto Adafruit Monochrome 1.3″ 128×64 OLED Graphic Display DHT22 Temperature…
Flat Boxes Update
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 and revision B, you see the difference easily. The corner in revision A has an…
Tall Boxes Ready for Download
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 shop are 20% off. The new set fits well into the series. In the picture…
