The 3D build animation that comes with the Slotbok jaws of life kit: every part going on in order, from the four MDF sheets to the finished tool, then the tool working as a cutter and as a spreader. The model runs on water in two 20 ml syringes, with no batteries and no motor.

The build, in short

1. Glue the 12 crosshead blocks together.
2. Build the body: base plate, first side wall and the two syringe holders.
3. Fit the slave syringe and clip the crosshead onto its plunger.
4. Close the body with the second side wall and the top cover.
5. Fit the cutting jaws on the pivot dowel, then the link arms and the jaw pins.
6. Join the master syringe with the tube, fill it with water and push out the air.
