Wanna improve the connection strength between your project’s 3D-printed parts, and also have nice clean surfaces? Instead of gluing bits together, or screwing plastic…
Looks like the Weller WE1010 takes tips of the ‘ET standard’ variety while these inserts are sized for Hakko’s ‘T18 standard’. They look pretty close, but not close enough for a proper fit.
It doesn’t look like we have a variant of this product that will fit your soldering station at the moment, but hopefully it’s helpful to know that only tips designed for the ET standard will fit your soldering iron.
