Those are mostly cosmetic issues, really…I wouldn’t worry about it, to be honest.
Thanks Nate, I appreciate your advice.
I actually weighed them both today and was a little surprised to find that the first Roller (with the gaps) weighs 75g and the second RollerM weighs 87g. Ryan lists these parts as weighing 90g each so the one I’m worried about is 12g lighter (~17%). Side by side they are the same height and the features line up so it hasn’t skipped entire layers.
I’ll print the other Roller and RollerM I need and compare the weights before deciding on if I bin it or not. Worst case is I use it as a spare.
If Ryan reads this, have you noticed any variation in weights over the parts you’ve printed or seen this before?
