Hey gang! Tim here from Core Electronics and I'm here to do an overview of my invention the onesie!

So, the Onesie is a 3D printable case for the new Raspberry Pi 4 model B and there's a single slide in and locked into place design, so you can 3D print a single component and then have a full case by the end of it. I have three different versions of the onesie, so we have starting from this side the “Onesie Stealth” here the “Onesie Maker” and over here the “Onesie Hat” each of these cases share a similar design heritage, offer heaps of airflow, little feet and nose access.

So, without further ado, let me introduce you to the Onesie Stealth. So the Onesie Stealth is perfect as a smart media box and worth noting, all these models you can find on “thingiverse” and if you ever want to print one then all the files you need you can find online or on our website. So the Onesie Stealth is perfect as a smart media box, it gives you access to all the all the plugs you need use your access to the microphone plug, gives you access to the two micro HDMI plugs, gives you access to the USB-C charging, the micro SD card you can access in like that. Here's your access to the USB-2 and the USB-3 and it also gives you access to the ethernet plug, all these plugs you can use all these plugs are function. Let me demonstrate to you how the lock part of the case works, it's locked in there it's not going anywhere, let me demonstrate it to you even more, it's not going anywhere it's fairly firmly in place. So, it’s perfect for when you want to have a stealthy looking case, something that tucks in and isn't conspicuous, it's just something functional, something practical and nice.

So, moving on we have the Onesie Maker, so the Onesie Maker shares the similar features of the previous one, so we have the two micro HDMI, you've got the USB-C, you've got the microphone plug, you've also got the audio out plug, you got the micro SD and all the USB plugs from the front as well as the ethernet and importantly because it's more of a prototyping device, something that you actually need to use all the pins for, we have access to all the pins we've got access to the ribbon cable at the front and we also got access to the camera ribbon cable there. These you can access very well and I'll demonstrate over here with this this is able to take a full line of header pins, like so and once you push that in that locks this case in so firmly and so securely it's not going anywhere, so it also gives ample air room for the CPU and that's the hottest part of these Raspberry 4s, they're not going to overheat unless you start overclocking them and if you start overclocking them this is the kind of case you want to be using. So it still has the same A-axis from the bottom and it's sturdy and it's strong, it's not going to let you down so it's good for say a workshop environment or more of a educating environment, one where there's lots of kids lots of people coming in handling these all the time putting them down treating them a bit rougher, it will it will stand to the test.

So finally we have the Stealth Case Hats, the Onesie Hat, so Hats a hardware that's attached on top and they're a thing that Raspberry Pi has been doing for a while and it adds so much more functionality to your Raspberry Pi 4s and all the kinds of Raspberry Pi’s but for this one case we're talking about the Raspberry Pi 4 model B. There's two official Raspberry Pi hats for the Raspberry Pi 4 model B and one of them is the sense hat which you can see attached right here and the sense hat gives you a LED matrix it also gives you a little joystick, very satisfying click too here’s your gyroscope, humidity, it gives you a whole bunch of functionality. It gives you a whole bunch of tools to make you be able to invent so this model gives you full access to the top, still gives you access to all the plugs on the side, gives you access to the micro SD and gives you access to all of these. Worth noting unlike the other cases which operate this slide in/slide out mechanism which I'll demonstrate to you right now because I pulled it out, slides all the way in, comes down to the very bottom make sure everything's straight and then cool beautiful little snap click, there it is again locked into place not going anyway, unlike that this one you need to install the Hat after the effect but it's important to put the standoffs on initially.

I'll show you exactly what I mean, so make sure you put these standoffs on before putting it into the case like so, you'll hear the same snap, there it is pull pin standoff, just like that and this I put over there, hat goes up right orientation, now with all those screws on, he's knocking in real quick just like that, lightweight and just like that your Onesie hat has been installed and it's good to go. So, when you're 3D printing these, if we jump over to the screen this is my overview online and it will run you through and also give you great images from all different angles of the Onesie family, it will also talk about the installation process which I demonstrated to you.

It'll also give you settings for 3D printing, I used a Ultimaker S5 to print these models and I used it on both normal and fast defaults, I'm not sure if you can notice but this was made by a fast and this is made via the normal. So normal is a 0.15mm resolution and fast is a 0.2mm resolution and when you print them, print them with this orientation facing upwards and now one that I prepared earlier is here, so one of the important things to note when you're printing out a Onesie, is that there will be a whole bunch of supports so I'm going to run through real quickly taking these supports off so that way you can finally have your finished component.

So start by pushing these in, I used a 40% infill, so it's important to note when you're pulling it apart, inside here you go deep into the bottom there'll be a little standoffs in there it's important to take that support off around there because that's what the board runs across so, just like that you have yourself a usable Onesie Maker. I'll demonstrate, Raspberry Pi 4 model B, just like that you got a usable component. Okay I had fun, I hope you guys had fun make sure you guys stay cosy and I hope you enjoyed this introduction to the onesies until next time! Signing out!
