RV AC units

I decided to try and make some RV AC units mainly to just see if I could do it. So tonight I took 3 small pieces of thick styrene and glued them together. After the glue dried, I took my exact or knife and carved out the basic design and form of the ac unit.
After I got the rough shape done I started filing down the edges. Then came the sand paper and the more different files to make the ridges.

I think they maybe too tall, so more sanding to come.

Tomorrow I will add some final sanding and then paint.

Stay tuned!
