Micro Drip System Gardena 1/2" - 6 ways 4,6mm

ABS made, didn't try other material
brim 3mm
slowest the best
print it with thread pointing upwards

the 6 holes are meant to receive 6mm aluminum pipe,
epoxy glued inside and outside
i find the whole item stronger made this way, instead of all ABS
regular quick connector will screw on it

the black 4,6mm hose fits great on the 6mm aluminum pipe
To make a hole stopper : cut a short piece of black tube, heat up one end, and press it flat with pliers
