Mod:Structures Plus/S+ Bookshelf

The S+ Bookshelf is a Structure in Structures Plus.

Overview
The S+ Bookshelf has quite a few differences compared to the standard, with the most notable being an upgrade to Metal Tier. Other changes include the ability to lock and pincode it as well increasing the number of inventory slots to 600. They can also snap to each other allowing for neat placement and/or compact storage.

Regular Bookshelf cannot be converted to the S+ Bookshelf, since the S+ version is Metal Tier.
