remodelled in fusion 360
i moved to fusion cuz it has a more vector like mesh rather than blocky mesh like in blender, I've used blender for 3 years, while it's good and all, fusion 360 is what I'll use for future hardware projects, I've only had these parts, I'm planning to put a pwm and an esc enclosure for it
, 8 hours is an estimate

more research on BLDC, blade models, Battery and duct design
Hours on researching different BLDC types inrunner or outrunner (Outrunner), sizes (2212 size), KV values (2200kv), ESC (30A mini BLDC ESC), fan blade designs, high cycle life high capacity high drain 21700 li ion cells (21700 EVE 50PL batteries), fan blade sizes to balance between blade length and central hub diameter, started designing the duct and the whole body in Blender, here is how it's going:

Research on BLDCs, fan blades, KV ratings, and power saving
I sketched some models on my notebook, all while in school... weird, but I have gone through many iterations, searching online for BLDCs, coreless motors, those turbo jet fans, axial fans, potentiometers, etc etc...
I've done this for weeks, and I think I wanna put an end to it by choosing one final method...
Outrunner BLDC, 3D printed fan blade (which I take from sketchfab and modify it a bit), attachment for air exhaust director, and 3s battery.
