Prusa XL scrubber brush designer buckets

Added some visual flair to what would otherwise have been quite a bland black surface on the fronts of 5 large buckets. Both buckets and slightly revised brush holder are cross-compatible with the originals. Paint the bucket patterns as desired. Gapless/soluble support interface highly recommended for both underneath the bucket hooks, and under the brush holder backside recess. Sci Fi Lines Vectors by Vecteezy
