These are improved knobs for the [Customizable Adjustable Glass Bed Bracket](http://www.thingiverse.com/thing:1949142) for the FlashForge Creator Pro and similar printers. These knobs have a **silicone gasket** incorporated in them, which acts as a spring. As an alternative, you can print the springs using a flexible filament. The problem with the original knobs and many other brackets designs, is that the thermal expansion of the aluminum bed is much larger than that of the glass (especially borosilicate glass). This means if you tighten the knobs while the bed is cold and then heat it, it becomes larger than the glass. This causes the brackets to lose their grip, allowing the glass to shift around.
These spring-loaded knobs solve that problem by keeping on pushing against the brackets ev
