Description

⚠️ Important Notice Before Leaving a Negative Rating!

To ensure a solid and durable assembly, this model relies on very precise tolerances.
Because of that, your printer must be well calibrated and your filament must be dry.
If these conditions are not met, parts may feel too tight or difficult to assemble. This is intentional for stability and not a design flaw.

Printing conditions: 3mf file / Bambu Studio Slicer / Bambu Lab H1C / stl not recommended!

***

This hand-powered vacuum cleaner CrankVac is a fully functional, mechanically driven device featuring a compact airflow system and a high-ratio transmission. The design integrates a double-stage planetary gearbox, a high-speed turbine, and a cyclone separator into a fully 3D-printed assembly.

The model produces real suction and demonstrates how mechanical power is converted into airflow using a compact gear reduction and turbine system. Its open and modular construction allows clear insight into the interaction between gearbox, turbine, and cyclone.

Key Features

100% 3D printed – no non-printed structural components
No AMS required
No screws, nuts, or metal parts
Tool-free assembly using press-fit and snap-fit connections
Hand-crank driven
Optional input via cordless drill instead of the crank
Compact double-stage planetary gearbox
Integrated turbine and cyclone separator

Important Notes

⚠️ Mandatory gearbox lubrication
Thorough greasing of the entire gearbox is absolutely required for proper operation and durability. Insufficient lubrication will cause excessive friction, heat buildup, and premature gear failure.
⚠️ Cordless drill operation
A cordless drill can be connected to the input shaft, but high torque and sudden acceleration may damage or destroy the hex interface of the first gearbox stage. Operate only at low speed and low torque.
⚠️ Material requirement
All gearbox components must be printed in PETG or a stronger filament.
PLA is not suitable, as it cannot withstand:
- friction-generated heat
- mechanical load
- long-term wear in high-speed gear applications

@user_2950936110

looks really cool but i cant print it because i have an a1 mini. could you make a version thats a1 mini compatible?

The designer has replied

@djx3000

Thank you! I have added a A1mini print profile. It is not a new creation, but a more specific distribution across multiple build plates. Due to the height of some parts, the model had to be split. The cut parts must be glued together after printing. At the moment, there was not enough time to completely redesign the model specifically for the A1 mini.

@picknic3d

Replying to @djx3000 :

Shame there isn't a specific one for the A1, most people won't print if they need to glue it as it loses strength and doesn't look as good.

@djx3000

Replying to @picknic3d :

I‘m sorry. This would mean to redesign the whole model. Currently I don‘t have time to do this.

It works! Material used : ABS for gears, PETG for the rest. At least for my part no drilling of holes was needed. After lubricating, it needed a few spins and then it rotated smoothly. Just a bit of sanding on gear edges was needed. Had to reprint 2 items (my fault, bad adhesion), but all in all printing was smooth. I also used a weak drill that is strong enough to provide some suction whithout concern of melting the gears. As expected they do heat up rather quickly. Great model!

Thank you so much for this great feedback! I’m really happy to hear that the model worked well for you and that printing went smoothly overall. It’s especially nice to know that no drilling was needed and that only minimal sanding was required. Thanks as well for sharing your material choices and your experience — that’s very helpful for other users. I really appreciate you taking the time to leave such a detailed review and nice picture. Enjoy using it! 😊

print was fine but after following the instructions nothing turned

@GH1125

I had the same problem, but when I left a review describing my problem, my comment got reported and removed.

@pavel_k88

I experienced the same problem. The issue was with the gaps between gears, they are locked too tightly, preventing any movement. What helped me was filing the gears and cage posts with a small file.

this is sick!

@user_1449927813

What kind of grease do you recommend for the assembly?

The designer has replied

@djx3000

I use regular machine grease from the hardware store.

@user_1449927813

Replying to @djx3000 :

Thanks! My son is excited to put this together. One more question, though.We are printing this with an A1 mini. Shouldn’t both of the vacuum tube segments have one expanded female end? Otherwise, I'm not sure how to make the two segments go together AND attach the hose to the crank shaft.

@djx3000

Replying to @user_1449927813 :

If you print the model with the A1 mini, I assume you are using the CrancVac_A1mini profile. Due to time constraints, I only “cut” the original model into smaller pieces for this version. That means the cut edges where the parts are joined should ideally be bonded with adhesive. Sorry that I haven’t been able to design a dedicated model for the A1 mini yet, but the effort required for that is quite significant.

im commenting again (PLEASE ADD A SMALLER VERSION PROFILE)!!! 🙏🙏🙏

for a1 mini

@djx3000

Thank you very much. Currently I‘m very busy and have no time for it. Lots of development hours are needed for that. Did you try simply to scale to model in the slicer?

@scorpinox4

Nice and good idea to create a vacuum without motors!

The designer has replied

@djx3000

Thank you!

@brandt369

This is why I love 3D printing as a hobby. This is completely unnecessary, but the 10 minutes of fun I can have assembling and using this is so worth my time and filament lol.

The designer has replied

@djx3000

I totally agree 😊!

This is definetly my next print! The idea is awsome! Will report back in a day or so.

Thank you very much 😊! Yes, I was surprised by myself.
