Designing The 3D Printed Desktop Fan:Our design aims for the resources we produce are quite consistent, we keep in mind that we will be 3D printing the design and once printed we want the result to be easy to assemble. Our main design aims were;
- Quick to design.
- Easy to print, minimal overhangs.
- Easy to assemble.
- To fit the assembled kit
- To incorporate the kits on/off switch.
- To be free standing.
- To move enough air to be useful.
Printing:We imported our STL files into Automaker, as shown above, and started our prints. The printing time, across all three parts combined, was approximately 16 hours. As were able to make our design without having to resort to support material, it was straight from printer to assembly.
Assembly:We used 5 x M3 Self tapping screws for our build but normal M3 screws will work fine. 1. Get your printed components, USB Fan kit and screws. 2. Push the USB cable through the hole in the bottom of the base 3. Slot the USB Fan board into the base and push the switch through the designated hole. (The holes on the board should line up with the holes in the base) 4. Screw 2 M3 Screws through the visible holes (No need to over tighten as this can damage the base) 5. Take the motor from the Fan Kit and push it through the oval shaped hole in the main body. 6. Push it into the centre piece of the main body with the motor shaft facing the front larger opening. ( this is a friction fit) 7. Connect the base and the main body by pushing together the two oval openings, the USB cable slot should face the rear of the fan. 8. Place the Front panel over the larger opening, aligning the screw holes. 9. Screw in 3 Self tapping screws. 10. Push the fan blade onto the motor shaft. 11. Plug into USB power and switch on.
