Tool Storage Caddy for Prusa MK3

Since I started using the printer, I've found I need the needle to clean the nozzle as well as a plastic scraper I made to remove stubborn filament on the printer sheet. The two hexagonal openings on top of the MK3 seems like a perfect place. 

I designed this tool caddy to fit easily into the opening without being too snug so that if the Z axis needed to move that high, the caddy would slide up freely.
