Both use the tabbed pole mount on the rear of the EAP allowing it to drop into the bracket.

One is a simple wall mount, the other is a freestanding table top stand with cable routing for 6mm diameter cable through the base.  Cut out allows good bend radius.  

Since taking the photos I have extended the slide 4mm so the end of the bracket does not show when viewed from the back.  

Printed without support in PLA+, layer height 0.22, 4 perimeters, 25% grid infill up to where the stand narrows narrow above the cable cut out then used a modifier slab to change to 50% infill for the narrow vertical.    Seems plenty strong enough for the task.  

Fan set to 10% for extra layer adhesion (only slight sag in the bridge at the top of the cable cut out but not visible)

Reduced speed to 75% about half way up as I was getting a bit worried about the vibrations in the tall thin section with high travel speed.  

From memory it used about 140g of filament.
