If you experience any leaks from your Grow Box, tighten this nut more in order to increase the compression of the garden hose washer against the inner wall of the Grow Box.
If you have difficulty attaching the nut to the Float Valve Receiver, try turning it over and threading it from the other side. Even if securing the nut is difficult the first time, it will "break in" after you use it once or twice.
Please Note: If nut is too tight, try this model (inner diameter expanded by expanded by 0.4mm. 3D printers vary considerably on how well they print threads.

Approximate print time = 18 minutes
Filament: Taulman T-glase, any color
Print temperature: 250C
Bed temperature: 0C - 70C
Nozzle size: 0.5mm - 0.7mm (0.4mm nozzle is too small to print t-glase)
Layer height: 0.35mm (do not go below 0.3mm)
Print speed: 25 - 40 mm/s (use 50% for first layer)
Filament flow rate: 90% - 94%
Infill: 100%
DO NOT use ABS or PLA. The model will be too fragile.
!! IMPORTANT !! You MUST print in a way that allows adequate layer cooling. There are essentially four ways to accomplish this:
1) Print 3 or more parts at a time so that each part has time to cool before the next layer.
2) Set your slicer to force a layer wait time of 15 seconds or more.
3) Print using a sacrificial cylinder object far away from your primary object, forcing the print head to move a long distance, thereby providing additional cooling time for each layer.
4) Crank up your fan speed to 100% during these layers.
