So.its a bulkhead I need to search for.
I doubted a decent seal in 3mm without a nut and seal.
I could even cope with an inline version that tightened in the middle so a push fit was either side. But can't find those either.

You want the face seal type then I guess use a nut to hold it tight. Something like this:

What is it for? I hope nothing important. Modifying a box like that is generally a bad idea, it will crack or leak. Any force on the hose and the plastic will bend, contents on floor.
I cant remember if clip lid containers are HDPE or PP but either will have too much creep for a bulkhead seal unless the seal was very large area.
Alternative, if you dont need the wide opening lid, a petrol tank for small tools etc.. many have a moulded or threaded section with suitable reinforcement for a hose barb.
Another option if it needs to be clear, is solvent weld acrylic sheets with a thicker peice, where you want to tap a thread.

Yes and no. A bulkhead fitting is meant to go through a bulkhead. It is not meant to seal against the bulkhead. To make it liquid tight, you have to supply your own sealing device (rubber washer, silicone, etc).

The big writing on the photograph saying 'printer potty' might be a bit of a clue:

Yes, could have looked it up but it may just be an example and its for something else...
So it appears Epson printers waste so much ink, that they require an external container
We had an Epson a long time ago, the print head continously blocked up. It seems the answer is, waste lots of ink...
Much better to bin it and get a printer where, the print head is built in to the cartridge. Fairly expensive for ink, but I believe there are ways to refil them cheapily and only when the quality starts to degrade.
I would not to use a plastic clip lock for this. If it goes wrong, ink will go everwhere. Repurpose a metal container that you can tap a thread into.

Cannon and HP don't like it.

Having slept on the question, I dreamed a dream...
An M12 cable gland provides IP68 protection so more than adequate fluid-tightness.
www.cablecraft.co.uk
The difficulty I see is whether it would crush the tube when clamped onto it. Maybe a short length of semi-rigid HGV tube can be used through the gland.
Also the tube might pull out, but you could put a blank cap on the end of the tube inside the box to restrain it and drill a hole in the end to allow the juice to flow.

Slightly different I made a small vacuum pot for my seed sucker/sower device but the principle of my turning is the same.
I turned a 10 mm fully threaded bolt to take a 6 mm pipe leaving 6 mm of thread , used flat washers & a nut as well as making use of the bolt's head either side of the plastic tub , sealed it at the washers & thread with red calor gas jointing compound . Is been in use for over seven years.
I did contemplate using modifying a cheap Chinese aquarium pump as a suction device to do the same task drawing the waste ink into an old coffee jar , again with home made unions . With the new HP printer we have a cheap supply contract that has never let us down , the printer it replaced was over six yr old, so yes the ink pad was sodden and gave problem prints a day or so before we replaced it .
