I thought I'd have a bit of fun with a few more bits of scrap/offcut pieces of wood. I made a drawing of the box and worked out a few measurements to fit the wood i had. Then i cut all the pieces i needed.
I got everything screwed up but didn't like the pieces along the roof so a cut another couple of smaller pieces that made the roof look better. I drilled the hole which is maybe too small . So probably have to make that bigger.
Then the fun part.. Painting.. So i thought I'd try my hand at camouflage paint. Seems to have turned out better than i thought it would
