Solved Filament Guide Springs Way Too Tight (E3D upgrade)

I recently upgraded my Robo R1+ to the E3D V6 nozzle. Yeah, I'm really really late to that party.

Anyway, things are going mostly well. However, ever since I reconstructed the carriage with the 3D printed replacements, the filament guide is extremely tight. It appears to be getting hung up on the two screws that are securing it in place, but I can't figure out how to alleviate it. It's like the plastic is catching on the screw's threads, but even if I lift the screws up, it's still getting caught.

It's tight enough that it's chewing up and breaking filament on occasion. I'm even having a hard time just pushing the thing back to feed filament into it.

Could I have missed a step reconstructing this thing? Everything else seems to be working just fine. I've already had a few successful prints. Any advice would be really helpful.

 

The setup is actually pretty much the same as the standard carriage. Hopefully these pictures are clear enough to make sense out of. I can try different angles if you want me to.

After playing around with it for a bit, I think what's actually happening is that the washers are getting caught up on the screw threads for some reason. I'm not sure how or why this would be happening here when it didn't happen on the stock R1+ carriage. They're all the stock parts from before, so it's really strange.
