Shouldn’t be a printing issue unless you printed the standard version and needed the IE version.
Start by loosening the bolts on all the moving parts. It is plastic and they really shouldn’t be tight, I’d say barely snug. If you heard any cracking while you were tightening the bolts you went way way way too tight. You can control the tension this way. Start very loose and when you get a few long runs under your belt and the bearings have seated themselves give a bit more tension on the bolts.
What size is your conduit 23.5mm or 25mm, and which version did you print?
