This speaker is distinctive in that it does not use any support material when printing, allowing the entire body to be output in a single print, and it is small enough to be printed on the Ender3 series.

There is no need to remove support material from the body or to glue the body together.

The stand, which is printed together with the body, can be easily removed after printing.

The bottom edge actually warped when I printed. Since the gap between the body and the stand is set at 0.4 mm for the purpose of making it easier to remove after printing, it is not possible to completely prevent the body from warping. Since the warped distance was only a few millimeters, it did not cause a major problem in terms of appearance.

A 0.6mm nozzle was used to reduce printing time, but it took 1D16H40M to print a single body (including stand) at a layer height of 0.2mm, 40mm/S, and 15% infill. It will be safe to print with brims at 8mm width.

The removed stand can be used as a stand for installing the speaker by gluing it to the base.

The speaker cable should be pre-routed backward through the hole in the chamber and attach terminals to both ends of the cable. Install the speaker drive mount in the chamber (be careful of the orientation). Apply adhesive (preferably the type that can be peeled off later) to the stopper inside the chamber before attaching the mount. After screwing the speaker drive in place, install the cover (be careful of the orientation). There may be some difficulty in installing the cover due to the accuracy of the prints.

The speakers can be placed horizontally or vertically without the stand, as well as in a layout with the stand.
