This is a fan shroud for a uBitx that uses the taller cases (i.e. those that can fit a 3.2/5 Netion) designed by Sunial Lakhani and sold on amateurradiokits.in. The purpose of this shroud is to direct the air flow from the primary fan over the finals. These get very hot when using digital modes.
The device is meant to attach to the rear 80mm fan and sit on top of the main board of the uBitx with the slots straddling the two large heat sinks.
This was designed using Fusion 360.
