Support for working on Ender-3 V3 print heads (& catching screws)

This box supports the Z axis of my Ender-3 V3 printers whenever I work on the print head. Those tiny screws are easy to lose (and VERY hard to find in carpet) if you have butterfingers like me. It's basically a wastebasket with a cutout for the X axis rod to rest in. One of my Enders doesn't have a "parking brake" to hold the Z axis position while extruding or retracting filament. It just keeps dropping due to the force of pulling on the filament from the roll. This fixes that problem for me as well and lets me apply downward force when I need to, like when clearing a clog.

IMPORTANT Remove the support bucket when you want to run the machine!!! (duh, but... you know...)
