This is to house your Super Tweeter Fostex - FT28D. Two Pieces but you don't need both pieces it just makes the Orb Stand higher and looks cool and both are in super hires. There are two ORBS one with just a hole for the wires and another is a hole in the back to insert a bnc connector or any connector that can utilize a 9.652mm hole.The Orb should print fine but the Base/Legs will need support and you will need 4 screws but those came with the speaker. Orb: Flip it on its face (the large flat part where the speaker is inserted) and it should print fine without any need of support but use at least 50% infill (can get away with 25% but it will sag more I think and not as good for the screws to screw into).
