The Jonsbo C6 ITX Tower has notoriously bad air flow. These panels let enough air through.

No supports, no additional parts required, just print an install.

I included:

• Meshed versions which I created inside orcaslicer with a modifier (15% 3D Honeycomb Infill, 0 top and bottom shell layers)
• Solid version for you to modify according to your wishes in the slicer
• STEP files for you to go crazy in CAD
