3D printing mini USB vacuum cleaner Loann BOUDIN | 205my the purpose of designing mini USB vacuum cleaner is the consequences of the chaos that I face after making it with plastic, wood for a few hours, and the electronic parts on my desk.
I needed a small and efficient device to clean up the mess, so I decided to design and make it myself.
This mini vacuum cleaner is very helpful!
I can now easily clean up my laptop keyboard, table and all the small fragile items I collect.
The following parts and tools are required for this project: Super Glue screwdriver 6x Pozidriv screw (
I found them in an old CD driver)
Knife/cutter flat clamp cutting pliers sandpaper heat shrink (4 mm diameter)
Soldering iron welding clamp 1x DC motor re-welding140 (
I chose this motor because it is common and easy to find in old toys.
If you decide to use a different type of motor, don\'t forget to change the SolidWorks file)
Old USB Apple cable (
From the nearest IPhone 5 or more)a switch (6*12 mm)
Fixed flexible pipe with Lego technology (
I used an old hose from a Lego toy)a tea bag (for the filter)
3D printer/3D printing service in most vacuum cleaners, the air of dust is sucked into the dust bag by the fan driven by the motor;
Then filter, when the clean air is left out, the dust is left in the dust bag.
In the 3D print vacuum cleaner I designed, dusty air goes directly into the filter and when the fan sucks the clean air to the top of the vacuum and rejects it outside, the filter remains
Now, make your own 3D print mini USB cleaner from theory to practice!
Let\'s start by designing one of the most important components of a vacuum cleaner: a turbine.
I already have several turbines in my toolbox with hand-held vacuum cleaners, but they don\'t fit my purpose.
So I decided to design my own turbine and for that I designed the turbine and other parts using Solidworks software.
Before designing the motor in the software, measure the motor first and imagine the future turbine.
When I\'m done, I can start drawing the turbine in Solidworks: first, I sketch the turbine I need and then squeeze the sketch out of 10mm.
After that, draw a circle on the top surface and then squeeze it until the bottom is 2mm thick.
To make the fan new, I expanded the base of cylender by 4mm with extrusion.
After that, I squeezed the very center part and made a pit to insert the shaft of the motor.
Finally, I made 2mm fillets for each blade and base to strengthen the turbine.
Other parts are created in the same way as extrusion, cutting and rounded corners from the material area.
This mini USB cleaner consists of 7 printed parts: I add everything to this manual.
The stl file for the printed part.
If you want to modify the part (
Use other motors, other USB cables. . . )
, I also include SolidWorks files, so feel free to use them!
This is not a problem if you don\'t have a 3D printer!
There are now online 3D printing services such as 3D hub, so that you can find the available 3D printer (a \"hub\")
Print your parts!
There are more than 18000 hubs listed on this site, so I believe there is a hub near your location!
Because I was curious, I looked at where the center closest to my house was: only 2. 2 km (1. 4 miles)! Impressive !
If you have a 3D printer, it is very important to prepare it for successful printing.
Full verification of the printer helps to avoid many problems when printing.
The amount of PLA or ABS should be enough to print the parts and the heating plate must be active and clean. . .
There are a lot of parameters to check!
I don\'t have my own 3D printer, but I can use the 3D printer owned by the electronics association I belong.
I learned a little trick when talking to a 3D printing expert: If you need to print fragile and thin parts (
Like a turbine, for example)
This piece is very important to stick to the plate.
But do you know that ABS and PLA plastic are very glued together?
When printed with PLA, a thin layer of ABS melt layer on the heating plate will make the part adhere to the plate.
To make this liquid ABS solution, mix small pieces of ABS with acetone in a glass container.
Finally, disperse the solution on the glass plate that will be placed on the heating plate.
Now you can print the parts you need for this project.
I used a homemade Prusa I3 from an electronics association I belong.
I also use the free software Repetier and Slic3r to drive the 3D printer.
After some wrong settings, the 3D printer is able to print the parts with good precision.
Before starting to assemble the top unit parts and bottom unit parts of the vacuum cleaner, make sure all the parts are installed together.
Printed parts must be assembled together as they are in Solidworks assemblies. The non-printed parts (
Such as motor, USB cable, switch)
Must be placed in their respective positions.
If not, use sandpaper and a knife/cutter to widen or reduce the printed parts.
The first step in assembly is to build the entire turbine.
Combine turbin_part1 with turbin_part2 and glue the two parts together with super glue.
Adding super glue to each propeller blade can cure the propeller well.
Once the turbine is fully bonded and assembled, we can now focus on the power supply of the vacuum cleaner.
The vacuum cleaner uses a DC motor powered by a computer USB port and can provide up to 5 v and 500 mA (
Enough to drive the motor).
Cut the cable IPhone at the end of the phone line.
The USB cable has 4 wires: one green, one white, one red and one black (or colorless).
The green and white wires are data wires and we are not interested in that.
The red wire is connected to 5 v and the black wire is connected to the ground.
Pass the USB cable through the motor holder hole and then cut the white and green wires with the cutting clamp.
Welding red and black wires, motors and switches in serial mode (see diagram).
Heat shrinkage is used to strengthen the welding and connection in the circuit.
Then, put the DC motor into the slot of the motor support section and the switch into the slot of the upper cover section.
Combine the two parts and screw them together using 2 Pozidriv screws and Pozidriv screwdrivers.
After that, put the previously assembled turbines on the motor shaft and glue them together.
The turbine is then covered by the turbine cover part, which is screwed to the motor support with 2 Pozidriv screws.
Finally, the USB cable is wound around the motor Holder section and the USB plug is sandwiched in the slot of his upper cover section.
Edit: Instructable member weeish noticed me in the comments section that adding capacitors and diodes in the blocking position can greatly improve the safety of the vacuum cleaner and prevent possible current spikes, which may break the USB port.
My vacuum cleaner has never had any problems, but to avoid any accidents, it is recommended to add both parts.
It\'s time to make the mini vacuum cleaner filter.
To this end, I used a tea bag: cut the rope of the tea bag and expand the tea bag.
Pour the tea into the container and it will be useful to test the suction of the vacuum cleaner later.
Then, extend the teabag carefully until there is a filter sheet.
After that, download and print the filter mode file included in this step: use it to cut the filter correctly.
Then, cut a line on the largest disk and wrap it around your thumb.
Insert it into the filter holder section and glue it with super glue.
The minimum disc is then glued to the bottom of the filter holder section.
Finally, the Le High-tech fixture passes through the hole in the filter holder section, which is screwed to the dust-proof tank section with 2 Pozidriv screws.
Assemble the top unit and the bottom unit together using super glue.
Finally, add the flexible pipe to the Lego fixture.
The dusty air will be sucked through this pipe.
The Assembly of the vacuum cleaner is now complete!
To understand how the vacuum cleaner works, plug the USB cable into your computer and turn on the power.
I tested the suction of the vacuum cleaner with sugar: it sucks sugar easily and makes the table completely clean.
In order to empty the tank, it is necessary to remove 2 Pozidriv screws.
Fortunately, this operation does not happen very often: the tank is large and may contain a lot of dust.
