Customizable mesh inserts to hide your messy electronics compartment.
The STL file includes 2 parts. Use split to parts to separate them in your slicer. On the inner part, set the top & bottom layers and perimeters to 0, then tweak the infill settings to create a mesh to your taste.
Remove your side panel, and insert the modesty mesh into place in the slot of the upper and lower extrusions, just behind the midpanel, then replace the side panel.
