This is the back of my 10" Mini server rack -- Custom made 3D printed power modules for each server

FYI, Codeberg/Forgejo can automatically migrate repositories including metadata: https://docs.codeberg.org/advanced/migrating-repos/#migrating-from-services

Way to head them off at the pass. Rock on with yo bad self.

xD

Thanks yea I made sure to add this Safety section to my write-up on how to build this yourself, and I reference back to it a lot, so it's painfully clear.

I printed this in PETG which can take the heat easily, but ideally you use UL 94 V-0 which is also flame retardant.

I did make sure everything is very well insulated, and pulled hard on every connection to make sure it's held down properly.

**Safety**  

This part carries live mains. Mains wiring kills people who get it wrong, and a fault in a printed enclosure can start a fire.  

Do not build it unless you are competent to wire mains and permitted to do so where you live. Sleeve or shroud all live terminals. PLA softens around 60 °C, PETG around 80 °C. Neither is flame retardant. Only a UL 94 V-0 filament is.  

Wire the protective earth if anything you plug in needs it.  

Build it at your own risk. I take no responsibility for injury, death, fire, or damage resulting from anything in this repository.  

Ya. I don't run more than 5A (basically a usb) through 3d printed stuff for that reason. Filament is designed to melt.

Yea each one runs through the previous module, so all the power goes through the first module.

IEC 13/14 connectors are rated for 10A (2300 W at 230 V) which isn't much lower than what you can run through your wall outlet. And in reality they can probably handle 15A(What your wall can handle) as they are commonly refereed to as "Kettle cords" and used by kettles which draw ~13 Amps.

That's very high, to give you an idea the 6 things I have plugged in draws ~240w, so I could chain up ~60 mini PC's and only then would I be over the ~2300w limit.

I do now mention this in the Safety section of my "How to build this" write up

I want it to be modular, so if I add another 2 servers, I can just add the server module in front, and its power module at the back.

Sure thing, there's lots more details on my GitHub Write-Up including how to wire it up etc.

Thanks!! Designing it was a BITCH, I knew almost nothing about CAD going into this, but hopefully my designs can help some others cleanup the power side of their racks.

It was a lot of fun learning though, and now I've made proper use of my 3D printer.

My setup is as resilient as this would be:

I haven't added any failure-modes

There are more duckies, a lil giraffe and a turtle at the front

Uggg don't give me ideas, I've already sunk way too much time into designing this 😅️🤣

So you could just put a relay between my power-module and your server, and it's problem solved.

A redesign to incorporate one of these would be great, there are also variants that monitor power draw, so you'd be able to see each servers power usage and switch it on or off remotely.

Why are you doing this to me?

My surname is Erasmus

erasmus is a perfectly cromulent name

I mean, Erasmus is a pretty well-known historical figure (and where, I assume, that programme gets its name)

That's where my mind went first.

Turns out we're both wrong and it's just OP's name like he said in the other comment, but I'm curious how you made that connection? Not passing any judgement on it, just curious since your brain reached a different conclusion than mine and I'm curious how you got there.
