from a place in UK.
I can look for details of that order if you need them ?

It's better to pay the extra £6 and get the metal one right?

It's better to pay the extra £6 and get the metal one right?

I've not tried that metal-one design,
the plastic ones work Great !

The teeth on Gear, that comes with metal design,
do Not appear to be Sharp enough, they look flat at tips.
So need to find out if original Gear will work with that design ?

Note: the metal one does appear to have spring-pressure adjustment
but I'm not sure if that is really needed ?
that may be handy if doing flexible or softer type filaments

(Personally I would go with the Plastic design,
since the original gears should work with them,
but you need to determine, for sure, that they will)

(The plastic ones, I got, Came with good gears but are slightly different diameter than originals,
so you need to find some extruders that Come with good, correct size, gears)
