Hi All,

Have had a look at my printer after a couple of years of not using it and a house move in between, and quite a few of the PLA parts have cracked.
I suspect I may have overtightened some of the screws, but am I better off reprinting in ABS or something else to avoid similar problems in the future?

Here's some photos of the affected parts

The Z motor mount crack is fairly common. There is a beefed-up design to replace it, on Thingiverse AFAIR.

Great thanks David. Will look to use that.
Was this the one you were thinking of?

Yes, that looks like the one that I used.

All of these (and more) have cracked over the years for me, I have reprinted them in PLA, just found a better ones, more robust so to say. And its all working nicely ever since.
