Handheld EDF

HI! i got a 75mm EDF and ESC from a friend and wanted to use it for something. As i tested it in a workbench with an arduion for a PWM signal i realy wanted to show my friends and coleags its power. Thing is it wasnt portable. A Problem with a Creative solution.

I printed it in PETG si it will be stronger and easier fit togheter. it wil propobly be easier to pint in PLA tbh tho.

Wiring:
electronics parts i used:
Arduino, XT60 Conectors, male-male dupont wire, 5K potentiomiter, Mini 5V DC-DC step down converter, PETG filament, ESC and the EDF.

I used the standard arduino example to create a PWM signal i wired straight into the ESC(the ESC is hidden in the handle, ik it should propobly have cooling but i have never used it long enoughf for it to be a problem). i used a 5K ohm potentiomiter to the A1 pin on the arduino and pin 9 to the ESC. The 5V and GND came from the step down converter and feeds the Arduino and ESC.

other Info:
the botom edf holder is not needed. If yo
