Completed DeskNano x300 - a 1.2L replacement for the DeskMini a300/x300

Okay, got the thing together (loosely) and it all works, thanks.
This print is just a draft really, going to print it much better when doing the final one when I get a better colour. Prusa MK3S+ with Prusament PLA.
Still need to get screws, a power button and some shorter wifi antennas!
The M.2 cover on the back is gold too.
Currently printing the 120mm cutout.
Thanks man for all your work on this.

Another color scheme.
Reflective Copper + Black, Black switch bezel, White Led, no HDD light.
Also did a thermal gaming test with the above setup to evaluate the impact of the mesh density.
Test setup (Gaming OC):
CPU: Ryzen 5700g, 4.4ghz manual clock @ 1.3v, SMT off
iGPU: 2250mhz @ 1.15v SOC
Memory: 4000mhz, 17-17-17-34-51, 320 tRFC
Cooling: L9A + A12-15
30 mins Witcher 3 - Max CPU 74c, Max Memory 40.5c.
Performance could be better, but it did hold up the pretty brutal OC config acceptably with the tightly spaced mesh.

Prusaslicer allows you to use 'modifier shapes' to change settings at certain areas of your part, which can be used to choose where to set the top and bottom perimeters to 0.
Orange is the part, green is the modifier block. The green block changes the perimeter settings where it interferes with the part. Modifier blocks can be cubes, cilinders, spheres, or even STL's you made yourself.
Sliced result. Have yet to print this though as my printer is at a friends place at the moment.
Lol, here I was the other day thinking pretty much exactly that "I wish I could use the support exclusion blocks to selectively implement 3Dmesh." Thank you for this. Have to play around with the slicer even more now! So many options and settings to find and figure out.
It works the exact same way, only difference is that it allows you to change pretty much any settings and not just support settings. Right click your part on the right panel and this is what you are looking for (pardon the Dutch):
After you positioned/scaled your modifier, you can right click that layer and select Layers and perimeters
So we are using different screws. The tray-side holes of the core are 3.2mm in the model, and I'm using these 3.15mm nominal (or .125in #5) self-tapping plastic/sheet metal screws to reach to the middle of the core while still not being too difficult to screw in.
I will look into slightly adjusting the tolerances (maybe an alternate version?) so that either type of screw will work, but in the meantime before I get to that, it should still work with 20mm M3 machine, by adjusting the horizontal compensation a little bit. This shouldn't affect your print scaling much, its just a small offset to the perimeters.
Cura has a specific adjustment for this - "Hole Horizontal Expansion". Negative value = tighter
and In PrusaSlicer Expert mode - there is a setting for XY Size Compensation. Negative value = tighter
It shouldn't take much, like -.1 to -.2mm

Thanks for this, I thought that may have been the case. I'll let you know in 7-8 hours. By the way in PrusaSlicer it's positive values to make it tighter, so I'm printing again with XY Size Compensation = 0.2.
I updated the default core on Printables with a -.2mm adjustment to the tray-side of the core (now 3.00mm in the model) for better compatibility with M3 machine or wood/plastic screws (recommended). The top side is unchanged at 2.9mm intended for M3x8mm. Thanks @kevpatts for your report.
So I had a little time to work on the GPU module. The first alpha version (0.4) will be put on Printables later and i'll be adding more revisions / versions.
It supports 2 slots and depends entirely on external power for the card and riser. It uses ADT R43UH (10cm).
Above is pictured with L9a+120mm fan and Evga 3060ti XC, it is about 230mm long, 105mm wide, 144mm tall (3.4L without power). The separation from the backplate is 9mm, necessary for the depth of the riser itself, but also airflow, and bend radius of the riser cable.
The shape is a bit weird due to the position of the m.2 slot, so the rear of the expansion card cannot be in perfect alignment with the x300 rear I/O. This adds about 25mm to the length of the card. But it could be much smaller by getting a shorter, or single slot card (< 3L).
The HDPlex 400w AC-DC roughly approximates the new HDPlex GAN which is ideal for this.
There is enough clearance below the card for your power connector, but not enough for an HDPlex power supply, so my current plan is to mount HDPlex and Pico sized units up top, and then examine doing ATX/SFX/FLEX versions that mount on the underside. It's also possible to angle the card and create a horizontal prism shape, and mount a small dc-dc power supply between.
The module will also have a surface hole pattern for attaching a cosmetic shroud to protect or fully enclose the GPU if desired.

No - the front I/O is the same, but the rear I/O is different, and there would need to be changes to the Tray as it was designed for the board.
However the H470 has the same front and rear I/O as the newer b660 version. And it has a similar board layout. So if I make a b660 version, it should also fit the H470 version, maybe with some small changes. If the socket position is the same then the lids for both versions would be compatible also.

Currently the X300s are sold out and discontinued...so I had to resort to H470 to build a mini PC for my dad.
It would be awesome if you made one for the Intel version as well! Would I at least be able to 3-D print the mesh panel and use it? or is that a no no as well?
