Fancy Oscillating Fan - Fully Printed

prusaprinters

<p>Update 1/5/2021: Flipped motor and moved gear to front shaft section, attached rigidly against the front bearing. Motor noise has been reduced significantly. Switched out 20mm M3 screws to 15mm.</p> <p>An oscillating desk fan, designed in Fusion 360. Everything is printed except for fasteners and electrical components. Optionally contains a rechargeable battery for completely portable operation.</p> <p>Fusion 360 link: <a href="https://a360.co/3qBHxLy">https://a360.co/3qBHxLy</a></p> <p>Video: <a href="https://youtu.be/vgS1dX1ZaXw">https://youtu.be/vgS1dX1ZaXw</a></p> <p>Base materials:</p> <p>| Item | Quantity | Notes | | --- | --- | --- | | M3x10mm bolt, button head | 19 | | M3x15mm bolt, button head | 4 | | M3 lock nut | 17 | | 130 size hobby motor | 1 | Currently using an 11.5k rpm@6v motor.

Everything else can be printed in a normal rigid filament, like PLA, PETG, or ABS. A lot of these parts have steep overhangs, so go slowly (especially for the blades) and use adequate cooling.</p> There are multiple motor pinion tooth counts included, allowing you to fine-tune the motor to main shaft gear mesh. I've found that a larger motor pinion results in reduced noise, so try to use the largest pinion that doesn't result in too much friction or motor load. <p>The main shaft screw includes a tight and loose version. Generally you should use the tight version, especially if printing in TPU; only use the loose version if it won't fit into the rear bearing.</p> <p>Finally, it's likely that the blades will need to be balanced. A good way to do this is with pieces of electrical tape; you may need to try out different tape placements to get the part sufficiently balanced.</p> </div></p></p> Category: Household
