This was such a fun build! For some reason mine will only turn on and off when it is plugged in, would you happen to have any idea why that might be happening? I can plug it in, turn it on, then unplug it and it runs just fine but when I try to turn it on without it being plugged in it doesn’t do anything.

@NoahAddis_375360 Maybe check whether the battery can provide the current needed to start the fan, as it requires more to start than just to keep it spinning. If the battery is at fault that'd explain why it turns on while charging, since the charger gives it enough current when plugged in.

I used a different switch and a different step-up but I made everything fit without any changes to the model (I designed a small adaptor for the switch and the step-up just floats between the cables :-)). Great design!

Very nice build, easy also to build. Tolerances are very tight, but I got thing to fit.

Fantastic project! Love the use of magnets. I cut out a piece of activated charcoal filter and shoved it in there. Works well.

Thank you very much for including the f3d file. It's still the one with the visible magnets in both versions by the way.
Unfortunately the construction dependencies are not robust enough to use the fan parameters to fit a larger fan. Changing to 90x90x20 results in unsolvable dependencies errors and kills the design. But then, this is not advertised as beeing parametric :)
So I just ordered a 80x80x15 fan, it's easier than trying to fix the errors...

@Robin Haha, I wouldn't have minded checking the design and fix the errors. Yes it wasn't designed to be fully parametric, the parameters are only there so I could adjust and finetune the values.

I really liked your project. If you agree, I can revise it by drawing a nicer circuit diagram using a design application. Additionally, I have ordered the parts I need, and I will start building it as soon as they arrive. While working on it, I can record the process and add a video tutorial

@Sezercik_2160538 Thank you, a proper circuit diagram would be nice. I'd gladly accept it, but only if it's not a hassle for you. I wanted to make it in a design app too, but after not finding any of the proper components I just went with drawing it by hand as it was faster.

Be sure to post a make when you're done, I'd love to see it.

@Vinark I am waiting for my orders via temu, aliexpress and amazon. I will share it as soon as possible. Thank you very much again. I liked your design very much

This is the best model for a fume extractor I've found. Thank you @Vinark ! I've printed it and all my parts just came in the mail. I'd also love a wiring diagram if you can, please.

@IamTimO_842090 Thank you! Multiple people have already asked for a wiring diagram, so I'll make sure to make one as soon as I can.

@IamTimO_842090 I've added a wiring diagram to the description.

Hello @Vinark, very nice project! Could it be possible to have the circuit diagram? An interesting update could be add a PWM controller to regolate fan speed :)

@maverickk89_253540 I've added a wiring diagram to the description.

Just to double check everything is good before I stick a battery in here... wiring goes from battery to input on charging board, (then out from charging board) negative goes to switch and then positive to step-up input, and then step-up output to fan?

@Fumanseano_113184 I've added a wiring diagram to the description. So you can check if you haven't wired it up yet. Which pole does the switch disconnect doesn't really matter, it can be the positive or the negative.

@GallegoJohnCh_993591 Unfortunately not, but I could provide a circuit diagram if that'd help

Cool Design, Had to modify the switch opening, my rocker switch was 19x12mm but everything fits together well. I bought the same fan as you, and was wondering which of the 4 wires did you use for pos and neg? I think the white striped is most likely ground, but I'm not sure. Thanks for the cool design!

@Fumanseano_113184 Thanks for the review! Yes, the white striped wire is the negative wire, and right next to it is the positive. I checked the pinout by googling 4pin WPM fan pinout, so I didn't have to guess.

@Vinark lol guess I could have done that! Thank you!
