We moved recently, and one of the features that drew us to our new home was a sun room in the back, about 9'x15', full of light and perfect for a workshop!
One corner is ideal for the laser, with a dryer vent for routing its (filtered) fumes outside. With two rolling racks for storage and two desks, I hope we'll have room for a small heavy bench and drill press stand. Good thing the Printrbot is (er, will be) small, we have big plans for this (not so) little room.
Funny to look at my "Workshop!" post from two years ago, most of those projects haven't advanced much, but the grinder timer has gone through a few versions and the flight suit ended up being by far my most complicated project so far.
