There is no need for multiple cables to power this wheel, just one USB cable will suffice. The maximum power requirement is approximately 120mAh @ 5V, so it can be operated from the Cooled camera's USB2.0 port.
When connected to a ZWO ASI6200, the distance from the filter to the sensor is about 18mm
ZWO recommend their 2″ RGBL filters which work well with the ASI6200MM Pro camera and provide nearly 1:1:1 RGB colour balance.
The requirements shown below must be met if using non-ZWO 2” filters.
