Snapmaker 2.0 Tool Head Storage Bins

Toolhead storage bins for Snapmaker 2.0 printers. These screw to the vertical linear modules and are sized to fit within the enclosure. Tested on A350, but should fit A250 as well: please report experience. Dual Extruder bin intended to mount at top of the rear vertical (furthest from enclosure door). It is orientated so the tool head can be moved to the bin without unloading the filament. The bin for the 10W laser can be mounted on the same vertical under the extruder.
