Thanks, but I'd ruled-out a DIY version of those because of the problems

Irrespective of any mode of blocking you are going to get the crud that
has fallen on the blocking mechanism dropping down when opening up
again, otherwise where do you expect this crud to disappear to?

Even with a bespoke fixed design consider how it is to be cleaned.
