Report on the Outer Sleeve
So I noticed that there seemed to be more play, than what I would like, between the arms and the outer sleeve.
Today one of the arms was jamming up, so I needed to pull the machine apart to sort it out, and that seemed like an ideal time to check out the outer sleeve as well.
Here’s how it looks
From the top
That ‘dirty’ patch is where the top clamp presses against it.
From the bottom
The compression indicated with the red mark, and that black smudge, was where the bottom clamp, next to the thumb hole, was squeezing in on it.
The yellow mark indicates where the bottom left arm had squeezed it in.
And the green mark indicates where the top right had squeezed it.
This sleeve was made from PLA - so it seems that’s just not strong enough for the task.
Measuring it again I’d say that I made it around 0.8 ~ 1.0 mm smaller than it should have been. ie. the outer diameter.
So I’ve done a fresh version, in PETG, and 0.6mm bigger OD.
