This is a static model of the repair and heal tools from Planetside 2. If you had never noticed, the heal tool is actually just a rail attachment for the repair tool. Real picatinny rail is modelled for the top of the repair tool, which allows you to attach anything you want up there. This is a static model, there are no moving parts.

Additional hardware: (heal tool only) 1x M3 nut 1x 10-20mm M3 screw These are required for the picatinny attachment of the heal tool.

The rest of the kit friction fits together, but may require glue depending on your printer's calibration.
