So here is a quick little one that was first mentioned by another forum member (in the UK IIRC) whose name I have sadly forgotten. But all credit goes to him for this one.

Correct. Round cross section. Size is labeled here as 1/4 inch. Matches actual measurement pretty good at 6.3 mm

Also commonly referred to as "backer rod". Brilliant idea.

Thank you for the credit. I used 10mm diameter but ensure it is closed cell meaning that water cannot penetrate. I trimmed the ends and glued them with contact adhesive, otherwise they fly off at higher speeds.

Great to hear from you @Rek With the one I used (yes it is closed cell of course) I did not have to glue the ends. And I definitely did test them at high speed
