DIY Desktop 5-axis CNC Mill

OK, you bought your router and you are happy with it. If you are an artist.
But... if you are an engineer... you probably are not so happy.
You cut some 2D stuff. Then try some 2.5D and start getting excited. And then, there comes a day when you start wondering... What if I can make something more out of my 3-axis router?
Then it comes to your mind that you can always convert one of the axis from linear to rotary! Yes this is it! You start doing it... you succeed, but deep down inside you know it.
You have to go all the way to the end and do it properly. You need to make the conversion to a full 5-axis machine to be satisfied! If you feel like it, then follow my lead...

An Unexpected Bioprinting Advantage Over COVID-19
Kerry Stevenson
Researchers have been using bioprinting technology to assist in the development of COVID-19 treatments.
According to a report in the New York Times, researchers at the Wake Forest Institute for Regenerative Medicine unexpectedly discovered a new approach: 3D bioprinted miniature organs. These human-like replications mimic much of the actual body functions, and thus are ideal for use in testing.
The miniature organs, which apparently include lung and colon analogs, offer a trouble-free testing platform that doesn’t risk any human or animal well-being. In addition, these miniature organs are far more closely related, biologically, than mammals that have previously been used for testing.
There’s another advantage in that these bioprinted organ analogs can be continually monitored, unlike, say the lungs inside of a test subject, which are a bit hard to access. In this way those performing tests can directly observe the effects of their prototype treatments.

First LIDAR 3D Scanning Apps Appearing
Kerry Stevenson
There’s now at least one new app that takes advantage of Apple’s new LIDAR capability.
A few months ago Apple unexpectedly announced a new iPad Pro model equipped with LIDAR. LIDAR is a range-sensing technology that is often used in high-end equipment for 3D scanning, particularly for landscapes. Seeing it appear in an affordable consumer tablet was quite a shock.
Apple’s intention was to provide additional sensor information to aid their Augmented Reality operations. In other words, when you’re pasting that virtual IKEA couch in your living room view, the couch is positioned more accurately.
However, the presence of a new 3D scanning sensor in an iPad obviously hints that someone would, sooner or later, develop a specialized 3D scanning app to make good use of it.
That now seems to have happened, with startup SiteScape now beta-testing just such an app

Toy Crossbow
NobodyNothing13
I started designing this crossbow in Tinkercad a while back, and it came out pretty well. After I finished, the design just sat untouched. Recently, I have looked back at my old design, noticing it still had many issues, like the fact that you had to use hot glue to assemble it, the striker was very short, nothing held the marble in place, it wasn't very powerful, and so on. So, I started refining this design, and fixed a lot of problems and made this crossbow easier to use, easier to assemble, more powerful and more accurate.
I made this toy crossbow to be a toy, and also part of a game. You can just launch marbles around for fun, but you can also play a game with these, with as many players as you want. In the game, you have a crossbow, some marbles, and 5 targets (I used plastic army guys). Then, you take turns shooting at your opponent's targets. You launch a marble, they launch a marble, and so on. I usually draw boundaries of how close your crossbow can get to your opponent's targets. You are eliminated if all 5 of your targets fall, and the last person who still has standing targets wins!
In the rest of this instructable, I will tell you how to print, assemble, and use this crossbow.
