IKEA blind part lost

Apologies in advance for this off-topic post.

My home has 11 IKEA Fyrtur smart blinds. Before mounting a blind, I disassemble the non-powered end to add a little silicone lubricant. Users on other forums have posted this tip so the blind will come down evenly, rather than the non-powered side lagging behind due to the increased friction.

I lost the white plastic bushing that goes into the tube. Hoping someone has cannibalized an IKEA blind and is willing to sell this bushing. I know it is a long shot, but it doesn’t hurt to ask.

Also contact iKea. It is possible they offer replacement parts for their products.
