Tips and Troubleshooting
If the hand isn't closing all the way, then...
-
There may not be enough water in the syringes. Add water until there's a total of 10ml between both syringes (not including water in the tubing).
-
The syringe may be taped too far from the hinge. Try re-taping it closer to the hinge.
