For the battery adapter, I used the model from this project: http://www.thingiverse.com/thing:3228348 For this model, I used a 65mm impeller and in my project there are two options for the blowing nozzle: using a 25mm pipe and a simple option. My project uses: - Electric motor 395 (12V, 20,000 rpm, shaft diameter 2.3 mm, shaft length 18 mm) https://www.ebay.ca/itm/1pcs-395-DC-12V-20000RPM-High-Speed-Strong-Magnet-Motor-for-DIY-Drill-Car-Model/224097329103?hash=item342d3ddfcf:g:rocAAOSwvmZfCBOk - 1x 608 Bearing (preferably without protection) - Button - Makita battery 12v - A piece of wire - Soldering iron - Superglue (for mounting the engine in the housing, for attaching the impeller to the engine axis and connecting the housing parts) - Tinplate contacts for battery adapter I used a 4000mAh battery. With a measured amperage of 1.85A (starting up to 4A), the estimated operating time is 1.5 hours.
