We weren't planning on doing an enclosure for the Ender 3, but so many people asked for it we had to go out and buy one and see what the fuss was about. The quality for the price is pretty darn amazing. The all-acrylic enclosure is the same price as the competitor's MDF box, but ours adds side doors and outside power supply placement. We donated both the printer and enclosure to the local Maker Space (for testing) and its now ready to ship. If you pre-ordered one it'll be shipping in the next few days.
It even got its own installation manual, but it wasn't written in time to include in the very first units shipped. If your kit doesn't include a printed manual just download it and print it at home.
