40 mm Fan Solder Fume Extractor
A bench-top fume extractor housing for any 40 x 40 x 10 mm fan — the fan bolts to the 60°-tilted face on its standard 32 mm M3 pattern (3.4 mm clearance holes with counterbores so the heads sit flush), and a 42 mm square of activated-carbon filter sheet press-fits into the 41.5 x 41.5 x 4 mm pocket in front of a ribbed finger-guard throat. Footprint 52 x 64 mm, 50 mm tall, with two M4 holes in the weighted base for bolting it to the bench and an open rear duct so exhaust clears the work.
Pi 4 40 mm Fan Cooling Bridge
A standoff bridge that suspends a 40 mm fan directly over a Raspberry Pi 4B / 3B+, with a 32 mm shrouded duct collar aiming the air at the SoC instead of letting it spill sideways. 74 x 64 mm plate on four 18 mm legs that clear the USB/Ethernet stack, 58 x 49 mm M2.5 board pattern with captured nuts at the board end, 32 mm square M3 fan pattern, plus side exhaust vents and a 26 x 4.5 mm slot for GPIO ribbon or camera flex.
