Anycubic i3 Mega - Small Tool rig

Remixed Anycubic i3 Mega Tool Rig by mjuddi, as i will probably never use most of the slots in the original design.

Slightly modified mjuddi's design to fit only the tweezers, scraper and pliers. As the remaining slots don't take too much space, i also rearranged them to have the same width as the frame mount.
