UPDATE: I uploaded the v2 of this model, easier to print and assembly. Compatibility with 3 fans 92 and 80 mm (SFF Mini ITX Case v2 by jagondela | Download free STL model | Printables.com)

UPDATE: Fixed some dimensional issues in the case model.

I designed this case thinking only the necessary in a reduced form factor and models which are compatible or made around the RTX 4060 LP. I must recommend at least PETG, I used PLA but is not the safest one.

For this you need:

• Screws 6#32, I recommend buy long screws and cut them with tweezers or dremel: 
  • 8 for fans (13mm long)
  • 4 for motherboard (5mm long) standard long screws works
  • 2 for pcie riser cable (5mm long)
  • 4 for PSU (5mm long)
  • 1 for GPU backplate hold (3mm long)
• 16 magnets (3x10mm)
• PCIe riser cable 180 degrees both connectors and 185mm long, I designed around this [https://es.aliexpress.com/item/1005006000973971.html?spm=a2g0o.order_list.order_list_main.5.2bd2194dgvI5wu&gatewayAdapt=glo2esp](https://es.aliexpress.com/item/1005006000973971.html?spm=a2g0o.order_list.order_list_main.5.2bd2194dgvI5wu&gatewayAdapt=glo2esp)
• USB 3.0 2x cable, the 0.3m is enough. [https://es.aliexpress.com/item/33046797763.html?spm=a2g0o.order_list.order_list_main.20.2bd2194dgvI5wu&gatewayAdapt=glo2esp](https://es.aliexpress.com/item/33046797763.html?spm=a2g0o.order_list.order_list_main.20.2bd2194dgvI5wu&gatewayAdapt=glo2esp)
• Power led switch button 60cm cable and 19mm diameter. For better fit, weld some different cables or use a low profile button, just needs to be 19mm diameter.

• 2 80x10mm fans.

• Flex ATX PSU. I used 400W like this, works really good.

• 4 scotch 21mm diameter rubber stops for feet

Print hints:

• For the case use this support configuration, enable the bridge support options
  
• For side panels use 10 wall count, no bottom and top layers, honeycomb infill at 20%. You can also switch to other infill percentage or pattern
  

Post processing instructions:

• Remove in print supports with your printing cut tweezers like following pictures
  
  
  
  Following cuts are not really necessary, but if you want to maintain the pattern, do it.
