Minimalist Brushholder for Citadel Paint Rack

Just wanted a small holder for brushes..

Snaps into the bottom rung of the Citadel Paint holder, has room for 6 brushes (one oversize)

UPDATE -- Just for inspiration, there's also two photos of a portable and semi-collapsible modelling kit I made recently, using collapsible paint holder/brush stand, collapsible bowl, and an old solid wood cutlery case I found at a local thrift store for $4
