  • Orca Barrel Mounts Loose in Upper

I printed a Orca 15 upper in Polymaker PET-CF and the clamshell barrel mounts slide in/bottom out inside the upper easily with just gravity, no pushing or hammering. Seems like the hole in the upper that the barrel mounts go into is slightly too large.

I've calibrated everything and I'm using the barrel mounts from Hoffman's kit. I previously printed the upper in PLA and that one had a nice snug fit, but this PET-CF one is quite loose.

Any suggesstions on what I should try or settings to adjust if I have to re-print the upper? I'm using OrcaSlicer if that matters.

It might need a higher flow rate, I've observed Polymaker PET-CF having looser fits as well.

Just for clarity (I'm seeing the same issue), are you saying higher flow rate for the clamps or the upper? Or both?

    I re-printed the barrel mount clamshell pieces with 0.05 higher flow ratio in Orcaslicer and then they fit perfectly the way Hoffman said in the docs. To do it properly I should probably print the upper scaled down slightly, but the mounts with higher flow seems to work fine so far.

    I didn't want to print the upper again because it's a 25+ hour print plus the cost of filament vs the mounts are just about a 4 hour print.
