Spherical speaker enclosure for 'Mona 2.1' speaker set

thingiverse

This spherical speaker enclosure is designed specifically for the 93 mm chassis Monacor SPX-30M, which serves as the satellite chassis for the 2.1 Mona 21 speaker set from ADW. The design features a single almost spherical enclosure, two long legs measuring 90 mm each, and one short leg measuring 70 mm per speaker. The vertical beam angle of the speaker can be adjusted by varying the length of the rear leg, with an angle of approximately 5° upwards. The legs have 5.9 mm holes that accommodate sawn-off M6 screws, which are secured to the sphere using M6 nuts from the inside of the enclosure. To mount the chassis to the sphere, four M3 nuts were glued into the corresponding holes in each sphere and carefully screwed in place with four screws per speaker. A hole for a RCA Jack Connector or cinch socket is located at the lower back of the spherical enclosure and can be secured from the inside. The sub-woofer enclosure was built as a classic wooden cube. My design was inspired by two specific things: the Mona 2.1 Speaker by ADW and the Circular Speaker. As you can see in the pictures, I chose white color for the sphere and black PLA for the legs. Giving the sphere its distinctive look required a lot of work, including grinding, filler application, grinding again, spray filling, and multiple coats of paint. The print time for each sphere was approximately 37 hours. To print the spheres, I defined support blockers around the inner support in Cura. This made it much easier to remove the supports after the print finished. I did not use this technique for the first sphere and had difficulty cutting out the circular support. The outer support required significant rework with filler and grinding at the back of the sphere, as shown in the pictures.
