Second Inventory

Simply a remote controlled cargo for getting the components you need into that tight spot.

Sorter automatically pulls items automatically into the next automatic cargo container in the automated storage line.
(Top cargo for input, bottom for pulling out)

Also has MMaster LCD Script (no mods needed) to display cargo of the Second Inventory. Simply press button to Refresh.

And a spotlight light with a button.

Edit: Encountered a practicality issue regarding component sizes. Steel Plates, Large Steel Tubes, and other larger components cannot go through small conveyor systems (small crate to crate). Gravity Gen and Radio Communication Components are unable to fit into a Small Crate in 1-1-1 Survival (components are larger than 125L crate volume). However, a medium crate cannot fit through a door, so a Space Engineer is the ONLY way to fit the largest components through a door (exceptions of kicking them through, but that leads to workplace hazards).

Edit #2: The new doors are awesome
