Egg Shaped Speaker

thingiverse

An egg-shaped loudspeaker enclosure, crafted using Tinkercad. The initial design accommodates a standard 4" (11.5cm) full-range driver. I'm utilizing a speaker that's been gathering dust, specifically designed for full-range drivers, making it simple to wire and eliminating the need for filters or additional components. Printed upright, without supports required, at a resolution of 0.2mm and a speed of 5cm/sec, which took approximately 15 hours to complete. Given its height of nearly 16cm, ensure your printer can handle this size. If the speaker exceeds your printer's capacity, consider printing it face down, though you'll need supports due to the inset ring for the driver. I chose wood filament for this project, having long wanted to experiment with it. After experimenting with various finishes on the first print, I decided against sanding – the lines created by the printer provide a satisfactory wood-like appearance. I've also tried several stains and ultimately selected "Old Baltic" by Feast Watson, followed by a clear glossy varnish coat. Refer to the accompanying images for the finished product (minus the unsightly stainless screws, which will be replaced with stylish black ones soon). A second version accommodates the Dayton Audio RS-100 full-range driver. Photos of the stained finished speaker demonstrate its appearance with these drivers. Be aware that these drivers are not inexpensive – they cost approximately $50 each (AU$), making it a considerable investment. I'm not an audio engineer, nor an electronics expert, and I didn't perform any complex calculations to optimize this design for sound quality. Instead, I based the design on what I believed would result in an aesthetically pleasing unit.
