Flair58 Gen 2 stem guider replacement?

So unfortunately, I accidentally left my Flair 58 Gen 2 on overnight.

This caused the plastic stem guider bit to overheat, melt a bit, get brittle, and break 😕

And to make matters worse, it looks like the replacements are sold out on the Flair website...

Has anyone had any luck improvising a replacement? Maybe 3D printing one out of something like TPU? (I tried looking online but couldn't find any STLs or other solutions....)

Would appreciate any recommendations!
