Citadel/Vallejo Paint rack

Paint rack for Citadel/Vallejo type bottles and some brushes. Heavily inspired by https://www.thingiverse.com/thing:2200560, I needed something a little bigger for a friend so these ones can hold up to 4*5 = 20 bottles.

Update (18/08/18): Added an even bigger Citadel version holding 6*5 = 30 bottles without brush holders. Updated model to be in the 'correct' orientation by default.
