Bambu Lab AMS With Hydra Modification Spool Centering Clips

I've had issues with some sizes of spools sliding over to the left sides of the slots in the Hydra AMS which causes the spools to rub on the Hydra frame and also ride right on the edges of the rollers which is causing them to wear down quickly. This extra friction and poor roller contact has also caused the dreaded “unable to unload filament” error that hopefully will be reduced by using these clips to bump to spools to the right and keep them from rubbing on the wall and riding on the edge of the rollers. 

There are varying amounts of centering available to accommodate different width of spools from 2mm to 5mm of spacer-ing. 

I've found a little variance in tolerance between slots 2-4 so you may need to scale up or down 1 or 2% to get a snug fit. I find the 3mm fits the best for my setup.

Currently, these only support slots 2-4 because slot 1 has a thinner lip to clip onto. I will design one that works on slot 1 shortly.
