The design reminds me of the unused "Repair Node", so:

Benefits

+ Slowly repairs nearby buildings
+ +50% Build speed on building


Debatable Stats

| This item replaces your dispenser


Consequences

- -50% Health on building
- -50% Healing to players
- -50% Ammo & metal generation & providing to players


Feels like this could go to that "Handy Partner" PDA, along with some useful alternative to the teleporters (probably jump pads & speed pads) since when it comes to repairing stuff, it is a "handy partner".
