Where can I buy a plastic foot - internal tube protection, square?

[Superrobban]

I need a single one that fits into a square tube that is 28 x 28 mm.

Hornbach has individual pieces that fit 25 x 25 tubes but that won't work.

The ones I find online must be bought in packs of 50.

3d printer is probably the solution here

Ok, it seems to work. I removed one from the trailer, it's supposed to be for a table leg.

Merry Christmas wishes!
