Someone must to packs of these punched or laser cut or something?

ebay for plastic caps
Not sure i'd want to weld the ends up myself. Open ends mean you can get a waxoyl lance in there for starters

Think you can get them from tifosi too!
No, I meant metal sheet to weld over the open ends?
He's not looking for plastic plugs, he want 1,5mm thick mild steel squares.
Bugger! Must type faster.

p.s cut to fit inside weld in grind off
Buy a strip of 25 X 1.5 or even 1 mm roughly the length you need to cover all + 15% and with shears cut off pieces slightly longer than 25 mm , weld
on 3 sides and grind 4th side flush with angry grinder then weld - easy peasy. 
I cut the lengths 25mm longer than needed, chop out 3 of the sides for a length of 25mm at the end, fold the remaining tab over and weld the three
edges.
If that's confusing, it's more difficult to describe than to do it 
I have cut a strip from leftovers of my steel floorplate.
Massive thanks to andyw7de for offering to cut some for me! Above and beyond!
