Y-adapter without pneufit

This is another y-adapter, but it will pinch the tube instead of using a pneufit (I don't like pneufit haha).

I'd rather print 2 half pieces, but there is a whole one if you want.

I polish it a little with emery paper to remove the imperfection of the print.

You need:
6 x M4x10 (only 5 if printed in one piece)
6 x M4 nut (same)
12 x M4 washers (not necessary,but better) (only 10 if...)

EDIT (09.05.18) : I modified the junction of the Y for a better move when the filament has been melt
