Completely reworked my mini oscillating desk fan model, one of my earliest Fusion 360 projects. The new design has been built from the ground up with a bunch of internal tweaks, resulting in significantly quieter operation and an easier assembly process. Printed the prototype in Prusament Galaxy Silver, which really adds to its vintage aesthetic.

Detailed list of changes:
- All fasteners standardized to M3x10 bolts and locknuts.
- Reprofiled base to fit standard 18650 battery holders, instead of requiring a lithium pouch cell. Battery life should be much longer as a result.
- Main shaft gear is now an internal gear of a much larger diameter, with curved spokes to reduce noise transfer. Motor pinion gear has a small cutout to achieve a similar effect.
- Motor/shaft drive gears now have larger teeth, requiring less precise clearances.
- Motor mount redesigned to allow adjusting gear clearance. Attachment points have been thinned out to reduce noise, with a TPU-specific variant available for even lower noise levels.
- Redesigned blade assembly with individually adjustable fan blades. Blades are much wider and have greater camber, reducing noise and moving more air. Subjectively, they look a lot better too.
- Front housing extended rearwards, with motor mount attaching directly to it instead of being sandwiched between front/rear shells. Allows opening up the housing without the motor mount coming out.
- Rear housing bolts are now exposed on the outside of the housing, instead of being hidden inside, for much easier housing assembly.
- Added a springy cutout at the bottom of the loop/handle component to reduce noise transferred to the base.
