it's a stick with a round base to fit on a painting handle and you can use Blu-Tack to stick youre pieces to it.

i don't have ideas for a good name if you do feel free to live a comment

you can print it vertically but if i's not strong enough i would print it horizontally (more support but the layers line are not weakening the piece).

if you want a cad file, just ask

if the pylon look ugly it's good, you have a bigger surface for blu-tack to stick to

EDIT: added a low adhesion stl, it has been hollowed out and chamfered at the base to be less painfull to remove from the bed withoud breaking the pylon. if you have poor bed adhesion or overhang wouldnot recommend it. 

disable supports or it become quite useless.
