Here’s the one I built:
I spent entirely way too much time on it, but it is awesome from a noise and dust containment standpoint. If you go the plexiglass route for windows, I recommend Tap Plastics. Decent prices and will cut the sheets to the exact size you want.
I’ll strongly second the above recommendations for leaving ample space inside. Also, getting the height right for ergonomics is worth the effort, especially if you prefer sitting at a stool while operating (like me).
