When ‘victorqedu’ was a child, he had an electronic puzzle game that enabled him to make various circuits from electronic components, such as lights, buzzer sounds, and even a radio. This fascinated him, and as “a programmer with a lot of hobbies,” it certainly had some influence on his life. He wasn’t able to find this game for sale today, so decided to build his own 3D-printed version, with component blocks that plug in to complete various circuits.

How to Fix Z Banding/Ribbing in 3D Printing – 5 Easy Solutions to Try
Most 3D printer users have experienced Z banding or ribbing issues at some point in their 3D printing journey, same with me. I wondered though, how do we fix this Z banding issue, and are there simple fixes out there?

900W Crazy Powerful Gearbox With SIX 775 DC Motors – 3D Printed
This video is viewer suggested. When two months ago I build this same thing using 8 micro motors then this time it’s upgraded to 775 DC motors. In design, I made a lot of improvements. For testing, I attached this new gearbox to a water pump and snow blower. This 900w gearbox has a lot of power…
Researchers Find a Faster, More Efficient Way to 3D Print
Two researchers at Penn State have created a new system for five-axis additive 3D-printing that reduces the amount and density of support materials needed for making printed objects.
In a paper entitled “Process planning for five-axis support free additive manufacturing,” doctoral candidates Xinyi Xiaoa and Sanjay Joshi proposed using a 3D printer with a movable build plate or extrusion arm to turn objects in 3D space as they’re printed, thereby making every surface “flat” as its being extruded.

3D Printing Custom Colors with Markers?!
Here’s one nifty trick big filament doesn’t wan’t you to know! Unless they sell a sweet transparent filament, that is…
In this video I dove deeper into the technique of using permanent markers to add color to filament before printing, testing various markers, filaments, and machines to see what works and what doesn’t.
Top 10 3D-Printed Gifts No One Asked For
Stores are shut and the mail is clogged, but you can still print breathtaking DIY gifts. If you have a Prusa, an Ender 3, or any modern 3D printer, consider this your ultimate Christmas gift guide. I hand-picked these prints specifically for gifting.
You don’t need anything except filament and common household objects, you can make any of them in a day, and none of them are difficult to print or build. Most importantly, all ten are dramatic, exciting, functional prints that your giftee will love.
3D Printing with VHS tape filament
If you have a pile of old VHS tapes collecting dust in your attic or basement that you know you’ll never watch again, either because all of those movies are available on DVD or a streaming service, or because you haven’t had a working VCR since 2003, there might be a way of putting them to good use in another way. With the miles of tape available in just a few cassettes, [Brother] aka [Andrew] shows us how to use that tape as filament for a 3D printer. (Video, embedded below.)
The first step of the build is to actually create the filament. He uses a purpose-built homemade press to spin several tapes into one filament similar to how cotton or flax is spun into yarn. From there the filament is simply fed into the 3D printer and put to work. The tape filament needs to be heated higher than a standard 3D printer filament so he prints at a much slower rate, but the resulting product is indistinguishable from a normal print except for the color. It has some other interesting properties as well, such as retaining its magnetism from the magnetic tape, and being a little more brittle than PET plastic although it seems to be a little stronger.

DIY Stream Deck (3D Printing, Arduino, Electronics!)
An Elgato Stream Deck is a vital tool for anyone looking to live-stream online, but the ongoing pandemic has made these devices hard to find or very expensive! To solve this problem, I built a DIY version using Arduino, 3D printing, and some custom PCBs, which you can also build yourself! All of the design files are free and open source so that you can create the Stream Deck that best suits your needs!
