Single piece Hexibase Tang Band Subwoofer (Fusion 360)

cults3d

This is a custom 3D printed subwoofer featuring a Tang Band W3 1876S 3" driver. The original design was adapted from Hexibase's fantastic creation using Fusion 360 software. I modified the design to print in one piece, eliminating the need for gluing. Key changes made to the original design include: * Printing in a single piece * Incorporating slots for captive M3 nuts * Adding a surface pattern showcasing the internal layout * Integrated supports for the chamber and driver cutout * Optional holes for M3 threaded inserts The design relies on supports for the chamber roof and speaker cutout, which can be generated through integrated supports or in a slicer. Removing the supports took approximately 15 minutes with care using pliers and flush cutters. I modified the waveguide cross section to peak rather than rounded top, creating a 45-degree overhang that prints well without support. A vaulted ceiling was added above the chamber for an airtight seal, with minimal direct support area. Versions of the file are provided with and without integrated supports. Terminal cut-outs were designed for binding posts (available on Amazon). The surface pattern can be emphasized by swapping filament color a few layers in (Prusa Slicer makes this process easy). Note that printing in one piece results in a heavy weight, typically over 1kg, requiring filament changes mid-print. Four holes are provided for threaded inserts like those available on Amazon. A test print of the chamber section is included to verify support functionality before committing to the full print.
