ERCT 180 degree coupler issue

[bartoszwas]

Hey,

ERCT 180 degree coupler block needs and update. Now design is almost perfect when pfe tube goes through whole coupler but nothing holds the tube on other end (not ecas side). Mine printer winded the tube on buffer wheel when filament got stuck on the end of the spool.

I think its just make the hole a bit smaller on the end to keep pfe tube in place.
