3D prints gone awry

Trying to print these fan brackets before I found the cause for the lack of plastic- this time it was the extruder’s idler bearing (in yellow block) bottomed out on the extruder body knuckle (green) when I tightened it a little more to reduce hobbed bolt plastic scrapings from the filament.  A little fining on the extruder body let the idler spin freely.
