Adjustable Outflow Adapter for Aquarium Filter

I made this thing to connect the angle-adjustable outflow nozzle to the spray tube outflow.

Print ball-head facing down, “spiral vase” mode. I added a brim to make it stick better.

I've included the SCAD file in case you'd like to make adjustments or want to use this as a base e.g. for a custom outflow.

Print time is ~8 min for vase mode, >25 min for 0.2mm layers without vase mode.

This definitely fits the JBL “spray tube”, but also any other tube with ~13 mm inner diameter.
