OOC:
Okay, roll an Average mechanics check to see if you find everything;
1 success: enough pieces to mock-up a piece of tech
2 successes: enough pieces to mock-up both pieces of tech
For each subsequent success one more piece of furniture/tool for the repair shop
A triumph: find a droid shell in good condition
