3" Cylinder Speaker Enclosure
thingiverse
Disclaimer, I am new to 3D printing and this is my first from scratch design. This is a small cylindrical speaker enclosure that I designed around the HiVi B3N full range speaker and Parts Express round speaker wire terminal cup. The B3N driver starts to drop off around 120hz so I sized the internal volume of this to provide a boost around 100-110hz, which I calculated in WinISD. To my ear and the not so scientific RTA app on my phone these do surprisingly well in that 100-120hz region, but it does drop off pretty quick below that. This certainly isn't an audiophile speaker design, but it's very compact and cost under $30 in parts from parts express, and another $30 in filament (Inland Copper Silk PLA from microcenter).
