DIY Film and Paper processor

An absolute crude idea to develop the paper is use something like,

and it can possibly develop papers upto 24x30 cm.

For 24x30 cm the required diameter is ~9.55 cm. So the above tube is 10cm in diameter.

Perhaps can buy a tray of size 30x40 cm or 24x30cm and fill it with water and roll this tube over it.

But I am looking forward to a device to rotate it uniformly either through hand crank or through electrical rotors. Any ideas?

My concept, paper up to 100 x 70 cm.

I am constraint by space and spouse. So I need a compact and less stinky solution.

Yes, I can scale it for bigger prints or for smaller films (10x15cm from plate cameras) but I want to ask about electric/manual rollers. How do you manage it?

Right now the simple is to fill water in a tub and roll it by hand but it may be cold during winter months.

Can you also show more about the tube on both the ends?
