Oh man, that must have hurt
Got my KP02 XXL yesterday, looks good but had a QC issue, foot broke off on the first articulation test, thankfully there was an extra set of feet included, same exact feet which I though was odd however I'm glad they were there.
The reason of extra foot is exactly for QC
We noticed on the first print of the body that Nilon of the peg was a bit fragile and we have a broken rate of 20% of pegs, that was too much for our standards.
So we printed new Foot with new pegs, we double checked the Nilon (that now is fine), and we added in the box extra two foot with pegs, so in case of problem you can use new foot
Prevention is better than cure!
Good idea!
