Grlle for drywall inspection and ventilation opening

thingiverse

I needed to construct a housing for radiators that rarely get used, so I built a frame that can be glued into drywall openings. It fits perfectly with the required grille size and design. This is an initial version - we printed and installed eight units already. Now it's time to test them and make improvements as needed. Depending on your print settings, some parts might need light sanding for a smooth fit.
