Ascaso STEEL UNO/DUO Water Tank Upgrade

My parents complained about the gap above the water tank of their new Ascaso STEEL DUO espresso machine. Flies and dust would occasionally get into the water, presumably through this hole (more holes on the back for pressure/steam relief valve, these are smaller though). I designed this peice to snap right onto the water tank with a tight fit to close the gap. A handy grip makes pulling the water tank out for a refill easier as well. 

I assume it should fit the Ascaso UNO as well as the water tank seems identical to the DUO, visible from product pictures. 

Watch out for the type of water tank you have! This one only fits on the reservoirs without the grip on the edge, which seems to be an update from ascaso. See the comments/makes for a picture. 

The top edge has a 45° face to allow for supportless printing as visible in the pic. Flip onto the face and add a good brim for bed adhesion. Printed well on my modified Ender 3 Pro. PLA with 4 perimeters, 20% infill. 

Please let me know if you have any suggestions for modifications!
