Pricing is planned to be $25 for a 3 Pack including US shipping. We'll see what we can work out for international... I figure by the 3Pack is about right for most people and balances off the shipping costs ($4 for first class pkg).

These inserts are slightly different than the originals:

- smaller tube 1.85mm with top chamfered out to 2mm.
 

- slightly longer (about .1mm longer)

This first batch Isn't quite "perfect" for some reason,

I'm getting a slight twist in the tubes... I'll work on that. They still work great though..

​

Best way I've found to install them is to put both the ptfe insert and the aluminum insert on a 1.85mm rod and insert into the nozzle.

 

Align the tabs to be parallel to the flats of the nozzle and remove the rod.

 

I also use the rod to clear blockages.. heat the rod with a heat gun to about 250°C and push the plastic through the insert.
