After having made the Modular Sound Bar / Center Speaker (https://www.myminifactory.com/object/41370) I continued my project of making a full set of speakers using my 3D printer. You could already use the modules of the Sound Bar as stereo and surround speakers, but for my situation I needed the speakers to have a little stand. Once I had done that and hooked everything up I found the high frequencies lacking a bit with the speakers I used so I added a tweeter. This is the result, again fully printable without supports. If you compare the sound bar with this unit you will find that I used different speakers - I have ran out of the units I got from China so I used some (more expensive) store bought (JayCar Australia) ones.
As with the sound bar, please let me know how you go if you end up making these.
