thingiverse

This is a wireless fume extractor for soldering. It uses a Dewalt 20v battery as the power source. I used a spare 80 x 38mm server fan I found at work for this project. Required components: 2x: Crimped spade connectors 4x: m3 x 25mm socket head screws 4x: m3 heat set threaded inserts 1x: [buck converter](https://www.amazon.com/Valefod-Efficiency-Voltage-Regulator-Converter/dp/B076H3XHXP/?_encoding=UTF8&pd_rd_w=IfI69&content-id=amzn1.sym.08900ed4-dd64-49b1-bce7-2e717defb1aa&pf_rd_p=08900ed4-dd64-49b1-bce7-2e717defb1aa&pf_rd_r=R60YM3H8SJB8CDY0Z1P9&pd_rd_wg=7QsGv&pd_rd_r=5b032223-1a4d-49be-a563-63c210b36ddd&ref_=pd_gw_ci_mcx_mi&th=1) to drop 20v down to 12v 1x: [PWM module](https://www.amazon.com/dp/B08HGNDCTN?psc=1&ref=ppx_yo2ov_dt_b_product_details) for fan speed control 1x: [Active carbon filter](https://www.amazon.com/gp/product/B004HSOWRS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) (about 10mm thick) 1x: 80 x 38mm Server fan Wire Assembly instructions: Crimp some wire into the two spade connectors and feed them through the holes in the Dewalt Battery Adapter bottom, then superglue the two halves of the battery adapter together while maintaining good alignment. Install the heat-set inserts into the Body so that they are flush or just below the surface. Cut a filter to fit the filter case, and install it and the fan into the Body. Wire up the electronics compartment according to the circuit diagram. You can hot glue the modules in place if necessary. Feed the potentiometer through the hole in the electronics compartment. Secure everything together with the four m3 screws. https://www.youtube.com/shorts/r3Uj__HBNtM
