The ronchi is very old and was given to me, the problem is the small size.
The 50x50 laser printer transparency from stellafane works fine but is better clipped onto a piece of etched glass to keep flat. I should try one on sticky-back transparency.

Sunfish, I see your Ronchi slide looks to be very thick though. I can see why the slides are so expensive if they are on optical glass that thick.
