A while ago I printed the Utility Belt. One of the main advantages of the design is the hinge on the back that allows you to raise the tophat. I quickly found that the whole thing would tilt up when I lifted the tophat to access the print bed.
My solution was to add some brackets to the front corners that tie into the top rails. This holds the Utility Belt down when the Tophat is raised.
The parts are easy to print (upside down) and use two of the nuts that you would have inserted if you followed the original instructions before fitting the utility belt.
