alternate to film cups / for thumbnails

I made these from 3/4" plastic tubing and a rip-tie.
The tubing is cut on an angle.
The rip-tie needs to be sanded after it's trimmed.
I used a regular hole punch to make a hole to pass the suction cup through.

I made 4:
I left 2 empty , passed a pc of creeping fig through another, and a very thin pc of plastic leaf in one.

I have seen my imitators in these several times.
However, the have not deposited eggs in any yet. ( these have been in the tank for about a week)
? One egg has been deposited on a leaf since I put them in.
However, they have plenty or water for a tad transfer?
We'll see?
I'll post a photo if they use them.

Larger diameter tubing may work for larger species?
I think home depot has 1" and 1 - 1/2" as well.
I'm on the hunt for clear 'green' tubing?
