First of all, let's get the bad news out of the way. The MDX-3 costs
$995, it can only mill 3D objects out of soft materials such as

6"x4"x1.6" envelope! If those three facts don't discourage you, then

desktops, right next to your PC. The interface to the MDX-3 is through

If these features haven't caught you, then you should also know that
the MDX-3 is relatively quiet (your wife won't send you to the garage
to do your work), and comes with debris shields to prevent you from
coating your desktop with particles every time you use it!
