This mods adds a repair pack with infinite durability, the Sonic Screwdriver (a reference to Doctor Who and old Factorio). Available for research after Repair Packs and repairs at the same speed as the vanilla repair pack. Not really overpowered since the vanilla repair packs cost almost nothing to make anyway just a small quality of life addition.

Update:
0.2.0 - Updated for Space Age. Quality increases only durability for repair packs, so higher quality Sonic Screwdrivers are pointless since they have the same stats.
