Made this model to accommodate auto filler float valve. 16mm hole for the autofiller I purchased from amazon. Great mod to never have to refill the finicky reservoir again! Model was made in Tinkercad and not perfect still learning how to do curves etc. Did a number of test pieces to get the correct pressure fit for the tank and am happy with the results. Will likely reprint in RED when I get some more PETG filament. Corrected for the gap at the back and moved the hole 5mm closer to the side in the uploaded model.
