40mm Movement Nesting Tray with gap

This is a combination of a remix I did of CrusherJoe's 25mm, while incorporating design elements from tbirney's Movement_tray design as well. Base slot has been increased to accept 40mm bases.

Updated 4/4 changed distance between bases, orginally it was 24mm from outer edge to outer edge, now its 24mm from inner edge to inner edge.

Increased the height of the bridge to match the height of the base lip.
