Posca PC-1MR Modular Horizontal Anchor

All the Posca marker pack anchors that I have found were desktop or placed on the lid, so I have designed my own modular system to be able to have all my Posca PC-1MR hanging on a shelf horizontally.   There are modules of 9 to 1 Posca markers and they can be combined with each other thanks to their simple assembly system.     Most of them can also be individually fixed to the surface using two screws, so you can print only the ones necessary to complete the pack you have.
