My existing panels are made slightly differently.
They are basically one whole shape, and the areas of the middle blockout is done via a printed layer of light grey on top, whereas these v3 seem to be two seperate half moon shapes and connected via two lanes at the back.
Even a small crease is causing them to break in the v3.
Im trying to see if a connection can be done from the back like the v3 panel
If you could source the correct color and then alter your shape of the panels with the connection a little different then it would be a good replacement.
