Fume Extractor with carbon filter

I’m new to 3D printing and I’m not using a 3D modeling program yet. All changes were done in Bambu Studio (adding/removing walls).Removed the screen opening (I don’t need portability)Removed the internal battery-holder bracketsRemoved the rear grills and made the back plate flat (similar to the front)Removed the screw inserts so the screws fasten directly into the fan from both sidesAdded 4 rear mounting holes to allow the screws to fasten directly into the fanEverything else remains unchanged. This is my first 3D print profile edit.For the components, I used:120 mm Arctic F12 PWM fanPWM DC motor speed controller/dimmer (5 V, 12 V, 16 V)PD/QC/AFC fast-charging decoy trigger board (small purple board)USB-C cable for power (charger output: 12 V, 2.25 A)Top model: 64g of filament (1h 54m print time)Bottom model: 60g of filament (3h print time)Assembled model dimensions: 42.8mm (D) - 154.5mm (H) - 128.2mm (W) Model will the potentiometer: 42.8mm (D) - 154.5mm (H) - 145.2mm (W)
