This remix aims to improve default geometry that connects to a fan. The Ratrig solution is a clever way of countersinking cylinder head screw but I found that it breaks easily when improper torque is applied.

This solution remedies that as now the printed plastic between shroud and fan is in compression only. The drawback is that the bolt head is no longer countersunk so button head screw is used to improve aesthetics.

The screw should now be 3 mm longer so use the same or 5 mm longer screw, depending on a toolhead.
