3D Printed USB Solder Fume Extractor (HEPA + Sponge)
Keep your workspace clean and your lungs safe! This is a compact, portable, and easy-to-assemble Solder Fume Extractor designed to be printed entirely on standard desktop 3D printers.
It utilizes a HEPA filter and a sponge pre-filter to capture particulates and extend the life of the main filter during soldering.

📐 Design Features
No-Solder Assembly: The rear housing features a dedicated cable port insert. This allows you to route the USB cable through the frame without cutting, stripping, or re-wiring the fan. Just slide it in!
Compact Footprint: Minimalist design that fits any workbench without being bulky.
Dual-Stage Filtration: Uses a sponge pre-filter to catch larger particles and a HEPA filter for fine filtration.
🛠️ Bill of Materials (BOM)
Fan: 1x 80x80x25mm Axial Fan (5V USB version recommended, but any other voltage will work with the right power adapter).
Print the Parts: I printed mine using PETG GF, but PLA will work either. No supports needed!
Filter Prep: Take the sponge pre-filter and slightly trim the corners with scissors to ensure a perfect fit inside the housing.
Cable Routing: Pass the USB connector/cable through the rear slot. Use the included small insert piece to secure the cable in place and seal the exit hole. No wire cutting required!
Stacking: Place the trimmed sponge into the intake, followed by the 80mm fan (ensure airflow is pointing towards the HEPA filter).
HEPA Placement: Insert the HEPA filter into the rear compartment.
Secure: Use the 4x M4x35mm screws to bolt the entire assembly together.
