I spliced longer cables onto the elekslaser after adding the z-axis attachment. To control the extra cabling length I:

1. Attached a ~6 inch stick to the end of the cable bundle using the cable sheath
2. Attached the 3d-printed LaserCableController to the z-axis attachment with 24-4 screws
3. Put the cable with the stick through the LaserCableController. It should be loose, but not loose enough to fall out

Controlling the cables this way allows them to wiggle, but still forces them behind the laser.
