The Breadbox (~2.3L box of fun)

Well if you make one that can take an ITX board, or if its easy to extend it so it will, I really want to print one tbh. School has 3D printers I can use(though this is a pretty major print so I'm probably going to have to pay for material) and I now have a spare ITX board around

That would be way too huge though

It may work if you printed it in sections and bolted/joined them together?

No I don't mean too big to print (although maybe that too now that you mention it) I mean it defeats the purpose of this build

Ah, fair enough, I guess after all breadbox is supposed to as compact as possible...

should end up smaller than the toaster so id say its stil pretty tiny, iirc the toaster is ~10.1L and i already find it pretty small

print size is definatly fine, im pretty sure you could print an MATX case in the print area of the largest one

With this at 2.3L, I'd expect an ITX version to be sub 4L, and with the ability to support somewhere around 185mm of graphics card.

Sounds pretty good IMO

I mean yeah

But the STX version is never going public

Yeah this is a special project, not just gonna give it away

^{(also I'd be too embarassed by my Inventor files)}

Make an ITX version, il keep it safe  

[TheRandomness]

Right, so, an update (finally lol).

I have decided to make a few changes to the design (again, also thanks @Ryan_Vickers for bothering to help ), most notably now wanting to include an internal PSU set-up. This is mostly for the fact that, well, power bricks are huge and I now consider them to add to the volume. Now, I'll be using the HDPLEX 400W AC-DC and DC-DC combo, and some sort of high-amp boost converter to get the 19V to the motherboard. The new design will be bigger, of course, but I don't see the total volume going over 4 liters. Now, I'm wondering if I should still print (I know, I know, this long and no print!?) the old design to sit next to the new one

I'm willing to bet it'll be under 3 litres still.  We really don't need to add that much more space.  Also, I wouldn't bother printing the old one, what good would that be?

[Bananasplit_00]

Over 4L you say? Good think I have a 3.5L in the works, without all this fancy super small mobo and special PSUs

An old memory. Back to the smaller days

I'm saying over 4 liters as a generous estimate

I wont judge you for not having fully constrained sketches, ushing the hole command for holes instead of sketched circles and proper extrusion techniques.... much

No no, nothing like that.  Everything is definitely constrained properly and I actually use extrude to make holes Although tbh, I would have thought that was the inferior option.  No, regardless I just feel it's a little bit of a mess, but maybe that's not even true... idk.

It's considered inferior because when designing parts for manufacturing, it's practice to use the Hole Callout command in the Drawing creation. This is useful for being able to call out the exact hole type; If it's threaded, counter sunk, if it's a pass thru hole or if there's an angle cut, etc.

Wait now you are saying the hole command is how you should do it?

Yes thats what I meant, might have worded it loose in my first comment but yes for holes that actually matter you should be using the hole command. If they're slots or generic hole cutouts for something like a 120mm fan, it's probably not as important, but when you have to use an ISO or ANSI standard Hole Command is your friend.

Ah, well, I believe the only holes that actually will be receiving a screw directly are the 4 motherboard standoff holes, and perhaps a couple in my little 90° GPU mounting bracket, and a couple that will attach some USB ports (if that survives the redesign).  Literally everything else I can think of is just a cutout for a cooling vent, IO, or a slot so things are adjustable, which wouldn't apply.  I'll keep this in mind though

Yeah those holes are fine. 

 

I believe the standoffs and most of the screws are #6-32 but I dont know if that includes the end that screws into the motherboard. That portion might be a coarser thread

This might make you cringe, but I believe the way we're going to do it is just make them small enough that it'll grab, and then the act of turning them in will make the hole into the right type Ah, the benefits of working with relatively soft plastic

Well If you're only using ABS then it's probably fine. I was under the assumption plans like these might actually be turned into metal constructions one day  In that case I would make the hole the minimum diameter of the screw so that only the threads are cutting into the ABS/PLA/Whatever material you're printing in. Makes for the least amount of warping of the material you're cutting in while giving the threads maximum material (kinda like drilling a hole for wood)

Sorry it's taking so long. But, well, I've direct access to a 3D printer now. Of course though, the design is going through some changes. Full internal power now, and at 3.2 litres.

I'm so excited for you to finish!! itx builds are cool as hell and the challenge makes it more fun looking
