This model is a remix of the mini ITX design by lightofhonor.
Challenged by my friends at VlogTehnica to modify and print this case for a mATX mainboard.
Somehow, the final design ended up being more suited for an ATX mobo.
In order to print it on my Ender 3 S1, I did have to extend the supports for the GPU. Since I was pretty new with working in Tinkercad, I ended up with very tight tolerances. To make the new GPU pegs fit, I had to sand them down a bit.
You will need 12 rectangular pegs to put it together and some good superglue.

I used 40% infill for the back and mobo pieces.
Used supports for the GPU pegs.
