120 mm PC Fan Desk Stand
A tilted stand that turns a spare 120 mm PC case fan into a quiet desk fan or bench fume mover — the fan bolts to the 105 mm square pattern with 4.5 mm holes that take either the stock #6-32 fan screws or M4, and the frame leans back 20 deg so the air goes at your face rather than across the desk. Footprint 130 x 92 mm, 114 mm tall, with a windowed base, cored side gussets and a pair of 4 mm zip-tie slots at the rear to dress the fan lead.
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.
