G 1 1/2 union fitting to 38mm (1 1/2'') hose connector

Use the .3mf files if possible, as the “union fitting nut G 1 1-2.3MF” contains a modifyer to have 100% infill in the critical section of the part. If you print from the stl, make sure the shoulder that holds the hose connector is printed with 100% infill.

Print each part separately. Best to print this from PC. A brim might be usefull.

I Only testet the part with a low pressure submersible pump. Be carefull when using it with high pressure like from a waterpipe.
Print the gasket from flexible filament or use a standard gasket.

The hose connector has reinforcing ribs on the inside, so it won't break easy even when there is some force applied to the hose.
