This 3D printed water pump is working with two engines and has a gearbox with a gear ratio of 1:1,5. This water pump is capable of pumping 410l water per hour. The body is printed with PLA but gears and turbine are made of ABS. I am sure that PLA works also totally fine, but I am a big fan of printing gear whit ABS.

How to build a Hidden Shelf Edge Clock – 3D Printable | Elegoo Arduino Nano | Smart Home | LED
I’ll show you how to build a very smart looking shelving system that includes a hidden giant clock in the edges of the shelves, and integrated LED downlighters to show off your favorite items on the shelves.
As the lighting is LED (using WS2821B ‘Neopixels’) you can choose your own colours. A discreet photoresistor also dims the LED’s when the ambient light levels drop – great for evening ambiance in any room.

3D Printing with Fusion 360 FFF
Additive Product Manager Sualp Ozel takes you through the new FFF (fused filament fabrication) functionality in Fusion 360 so you can 3D print straight from Fusion 360.
Note that the Manufacturing Extension is *not* required to use FFF in Fusion! Happy printing!
This 3D Printed Flip Clock is Worth a Second Look
Flip clocks: they were cool long before Bill Murray was slapping one repeatedly in Groundhog Day, they were cool in 1993, and they’re still cool now. If you can’t find one on the secondhand market, you’re in luck, because [iz2k] has laid out an extensive blueprint for building a gorgeous retro-looking clock with some modern touches.

How to 3D Print more Accurately so you can make Lego Bricks
3D Printing doesn’t always have to be accurate. But when it does, you need to know the steps to make your 3D printer behave.
OctoScreen – Octoprint RaspberryPi -Touch Screen Plugin – Chris’s Basement
We take a look at the Octoscreen plugin for Octoprint. This will enable the ability to use a touch screen hat for the raspberry pi. A nice simple interface for octoprint. This is how to get it set up and running.
Properly Configuring a Camera in OctoPrint
Most people that I talk to in the various 3D Printing communities I am a part of simply plug in a Raspberry Pi Camera or USB Webcam and run with it. People do this without even considering that settings could be tweaked to make the video captured by these cameras better.
When I started looking into just what could be done to optimize cameras in OctoPrint I found that much of the information available was either outdated or a raw data dump that was not easy to read (or act upon) for most users. With updates to OctoPrint, a lot of information has changed and most of the information on this subject has not evolved. Because of this, I thought I would try my best to summarize what I had found and updated to the latest version of OctoPrint in an effort to perhaps save some of you some time.

Innovate Asterisk Unveils a 3D-Printed RaspberryPi 4-Powered Tablet
Voice-over-IP specialist YouTuber Innovate Asterisk has published a step-by-step guide to assembling a Raspberry Pi-powered tablet, comprised of common off-the-shelf parts and housed in a custom 3D-printed case.
“The concept of the project is to develop a 3D-printable, Raspberry Pi-based tablet. All parts (components) must be easy to obtain and readily available,” Innovate Asterisk explains. “It must have a battery, and it must be the primary source of power (meaning, it will charge up with a cable plugged in, but must have enough power to run without it.) It must be able to operate perfectly fine without a keyboard (meaning, everything in the user interface should work without an issue even if you don’t have a keyboard and mouse plugged in.)”
Orange Adventures (Part 1)
This has been my inaugural adventure with a resin printer, complete with a new project and a sound demo.
Czinger 21C: the world’s first 3D printed hypercar | Top Gear
The Czinger 21C is a 1,233bhp 3D printed hypercar complete with a turbo V8 revving to 11,000rpm, a 1+1 layout and $1.7m price tag. Oh, and the big news is it’s 3D printed. Well, large sections of the chassis are, paving the way for a revolutionary new car manufacturing process that could change… everything. It’s mind-blowing stuff, so let Jack Rix be your guide around California’s Koenigsegg rival.
