Stele ATX PC Case

A stele (/ˈstiːli/ STEE-lee), when derived from Latin, is a stone or wooden slab, generally taller than it is wide, erected in the ancient world as a monument.
The Stele is heavily inspired by the Motif Monument and I recommend checking it out if you are working on an ITX minimalist build.

-About as small as an ATX case can get (approx. 22L)
-Open chassis
-Lots of slots for ziptie/velcro strap cable management

-STEP file of full assembly included
-"S" versions of files include some built in support for printing

3D print Settings:
I printed in PETG for temp resistance.
Some PCs may get too hot for PLA.
I have included "S" versions of some of the files which have some support material built into them.
Several of the parts require the use of supports depending on print orientation.
