Now the biggest issue is maintenance (well, besides dodging the acorns that seem to be continuously falling).
I built my stone mill back in 2004 and it really looked good then. (Originally documents on another site - so that log is gone. But you can see it here.)

I made the windows out of styrene…and also glazed them with styrene - it feels like about .010" thickness.
Well, needless to say, the mill has suffered being outside for 13 years…
In 2008, it got a new roof, as the original was just too thin and rotted away. The roof looked pretty good, but the windows were already in trouble.

Pieces of the thin styrene have fallen off and the “clear” styrene was turning frosty and yellow.
A picture from a few days ago shows even more window deterioration.

I THINK that IF I had used acrylic for the glazing that I might still be OK. The styene sticks to that very well using acrylic cement - and the cement doesn’t fog the window at all.
Anyway, I decided to replace the windows. I tried ordering some and cutting them to fit, but that was pure aggravation plus tedium.
I have been thinking about a 3D printer for some years and finally decided to give it a go.
I ended getting the Qidi Tech X-ONE2.

I was very apprehensive that this would take a LOT of tweaking to get it right, but I was pleasantly surprised to have it print perfectly the first time out.
I had designed my window in Tinkercad - a free online tool. It worked wonderfully and I used my design as my first test print.

It was fascinating to watch the window being printed. But even more exciting when I removed the “print” from the printer.

Wow. I couldn’t be more pleased.
I primed and painted the windows and then glazed them with some 1/16" thick acrylic, glued in place with liquid acrylic cement. Today, I started replacing the windows.

The roof was removed so I could glue these in from behind. I used silicone cement to hold them in place. (And for some reason, this picture gets rotated left. Open in new tab and it shows the correct orientation. Why? Because.)
When all done, it sure looked a LOT better.
