One portion of your design appears to be not well suited for FFF printing. The "points" of the extruded star shape will not be pointy using filament type printing. Are you willing to have slightly rounded points, or do you require them? If the latter, you'll be seeking a print completed by MSLA or similar methods, which will increase the cost.

In the orientation shown, support will be required for FFF printing. With a vertical orientation, the layer lines will be perpendicular to the main axis. Is that an acceptable configuration?
