I've been having issues with the fragile tab (used to hold the fan cables) snapping off during assembly, as it snaps across the layer line when applying a minute amount of pressure.
Admittedly, this doesn't affect the operation of the Nevermore, just means a less tidy install of the wires as they don't have an anchor point.
My fix for this was to add two small holes for a cable tie to slip through and secure the fan cables. Designed for cable ties measuring 2.5mm wide and 1mm thick.
Use the fan clips from the original model.
The author remixed this model.
