3D Printing

Parts List

STL files for 3D printing are oriented to print "as-is" on FDM style machines. Parts are designed to 3D print without any support material. Original design source may be downloaded using the links below.

  • buzz-mount.stl
  • buzz-control-box.stl
  • buzz-back.stl
  • buzz-cone.stl
  • buzz-diffuser.stl
  • buzz-speaker-cover.stl

CAD Assembly

PCBs are secured to a mounting plate with M2.5 hardware. The mounting plate is secured to the speaker cover using M2.5 x 16mm long screws and hex nuts. A toggle switch and tactile button are panel mounted to the back cover. The speaker cover snap fits onto the back cover. A diffuser is press fitted into the opening on the top cover. The top cover snap fits onto both of the covers.

Slicing Parts

No supports are required. Slice with setting for PLA material. Use white or translucent filament for the diffuser. 

The parts were sliced using CURA using the slice settings below.

  • PLA filament 220c extruder
  • 0.2 layer height
  • 10% gyroid infill
  • 60mm/s print speed
  • 60c heated bed

Design Source Files

The project assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, STL and more. Electronic components like Adafruit's board, displays, connectors and more can be downloaded from the Adafruit CAD parts GitHub Repo.
