I have actually been considering this myself.
I have some video of the routine and will try to put it online.
The design here is made of 6mm or 9mm ply.
The sides are cut with a slot that fits onto the stage. This will help keep it steady while it is being turned.
The funnel at the top could be square or round. I expect to find something that can be adapted to this purpose. Perhaps some cheap aluminium kitchen implement?
The handle should be decorative. I think the visual effect of it as an over the top gadget should be considered. Here is a good example:

The handle would need to be clear of the stage and easy to turn.
Black cloth can be attached to the open back to hide hands and puppets coming down if necessary. I had considered making it come deeper into the booth so the hands could come in through the bottom but I think this would make it too cumbersome.
The sausages that come out are usually in the colour of the puppets that go in. The baby white and the constable blue or checked. Martin Bridle has a thief in stripes go through. I thought once you had established this pattern you could vary the gag by having green ones. A puppet could go in and when the sausages come out green the comment could be "Must be a vegetarian." Chris once suggested you could toss in socks and spotted underwear and they could come out as on a clothes line.
You could lift the puppet up out of the funnel and have the sausages go back in. It would require coordinating Punch lifting the puppet up and the other hand pulling the sausages back in. This would look funny and help make the routine more absurd and less gruesome.
I found that most shows that use the sausage machine it tends to dominate the structure of the show. So it would be a good thing to do if you are doing shows in the one location throughout the day.

and below is the round version.
This could be made with large cardboard tube onto which carpet is wound. This is usually thick and of a suitable diameter. The top of the funnel can be flared by cutting slits and inserting V shapes pieces of same cardboard. The front could be a circle of MDF. It could then be painted with metallic paint.
