1/17/2026 - designed the body in Fusion 360

After my brother let me use his phone, and said: "No instagram, no whatsapp, no tiktok", I go to youtube and open incognito mode, I search up "Fusion 360 Full Course", then I watch 3 videos, 25m total, when we got home, I started designing it in fusion, just from 6pm to 11pm, which is around 5 hours, I made this (don't mind the stator blades, I'll cut them off later)

it was a pretty quick design, then I went to google and search up for the perfect BLDC for this, I wanted it to have a tip speed of 40m per second, so I calculated I would need 1900kv rated motors, but because those are pretty rare on my local indonesian online marketplace, I decided to go lower, and also bcuz it consumes more power which is not ideal for long hours, so I decided an 1806 1700kv motors, as it will have a tip speed of 32m per second, and around 20m per second maximum air velocity, I hope... and for the batteries... those are easy, just use 2 5Ah lg chem m50 lt, my fav cell, gets the job done, high enough discharge, and for the esc just use 12A or 10A micro esc... and for the pwm, use a pwm module, and a sliding potentiometer... cuz better feel, yk, whatever, I'll keep modelling it until I'm satisfied... time is modelling time + research time on motors and whatever etc

1/19/2026 - fan blade tuning, checking component availability online

I took some models of fan blades, and compare each, decimate unworthy designs, and modify some to fit a 1806 bldc, I also checked the availability of some components online suck as the motor itself, esc, servo testers, for the battery I'll be using EVE 50E for its high 5Ah capacity and quite the good cdr rate of 10A, which is just enough for this motor, also gonna add a 2s bms 10A rated so the esc doesn't die, I'm still deciding whether I use a micro controller for fancy, futuristic, modern, and sleek speed controller or just use those generic mini servo testers

1/22/2026 - designing the motor mount, putting holes for screws and stuf

here is it, it has 7 blades, motor mount with m2 screw holes, the motor hub has the scrw holes too, and the design is almost ready, just need to add some holes for the potentiometer and buttons, at some point I thought thathigher voltage and lower KV motors would be more efficient, while it is true, I couldn't fine any 18xx series motors that has 500kv for 24v or 1000kv for 12v, so 8v at 1700KV ratinng should be good enough... I hope it'll be

1/25/2026 - resized screw holes and tweaks aerodynamics

for the aerodynamics, I initially used a teardrop design as an airfoil for the stator blades, it wasn't the best, obviously, so I gone through some naca airfoil profile generator, and found a perfect match! 0416 4 digit profile, I hope this is better, so I downloaded a fusion add ins called airfoil generator to make a sketch of exactly that in fusion without having to convert .dat files or whatever idk about those, then I remade the mount so that they fit the screws more, from 2.4mm hole to 1.75mm hole for pilot holes, I think it'll do better, and I was so confused, like literally what even is boss diameter? does a boss have a diameter? absolute hysterical nonsense, it was the screwholder or something, I split the handle into 2, and figured out 4 screw holes are enough, and...wait that's just a maybe... anyways i'll fix that later, I did some sketch cylinder, extrude, extrude, extrude, extrude... Extrude... I'll be using 2 m2x8 screws and 2 m2x14 screws for he case and 2 m2x5 screws for the prop, idk how to use a brass heat insert... and I redesigned the duct so that it has a converging nozzle, it's not noticable, but it'll improve airflow a bit... oh also I've added the usb port hole and the potentiometer hole and the tact switch hole for the speed control and power button, still figuring out how to implement an rp2040 into them, but overall everything's looking good, turns out my laptop charger brick has the same length and width as my handheld fan's handle, my design has bevels or fillets so it'll be way more comfy to grip, when the design's done (which is almost), I wanna yk code them, I already have the functions in mind, like soft start, press hold or something

I spent way too much time on the modelling...

1/31/2026 - FINALIZING THE DESIGN!!!

FULL DESIGN, ALL MADE IN FUSION 360, DESIGNS WERE MADE FROM 0, I HAVE SO MUCH PARAMETRIC STUFFS ON MY TIMELINE😭😭 btw... I made it to fit all of the stuffs, but I may need to cut wires so that it all can fit without those bird nest cable all over... tbh I just need to have the firmware set up, and it'll be just perfect!

2/1/2026 - Resize screw holes to fit brass heat inserts

these heat inserts are just 35 cents for 10 piece, I couldn't find other compatible heat inserts that are this cheap and have this low MOQ

I resized the screw holes from 1.75mm (prone to cracking or splitting due to the orientation) to 3.2mm (kinda would fit the 4mm OD heat inserts)

2/2/2026 - put all the files together

I have put all the firmware this and that... and trying to reorient the parts to print, the parametric timeline has a whole lot of parametric thing, so it may cause the lag that slows down the reorientation process, and Ive wrote the github readme all of those
