M3 Bed adjustment thumbscrew

A thumbscrew for easy adjustment to your heated bed. It works by inserting a standard M3 bolt into the bottom of the model and routeing the bolt through the top. This makes for far more precise adjustments. It is best to print it at a .2 mm resolution with an infill of 10 percent. This makes for a fast and strong print. Included in the model is a little support for the hole. You'll need to remove that afterwards, it's easy to do with a small screwdriver or pliers.
