Dual Nano MAT 4" filter sock adapter for fuji cube

Nano Mat adapter for fuji cube sump dual 4" filter sock.  

This adapter takes place of the 4" filter sock provide by fuji cube. The adapter slightly lowers the nano mats in the sump, so the water sensors work more independently while also providing a better watertight fit on the gasket. 

Printed from translucent PETG, some light sanding and chamfering of edges maybe required for a press fit. 

A lid is also provided to replace original cover
