Air assist for fixed focus laser with 5015 fan

Last crawled date: 4 years, 3 months ago

Not really air assist, i do not think 5015 fan have enough flow rate
Had panic attacks seeing smoke ignite right under the lens of my laser, so I sketched this, as there was nothing suitable for short focal length lasers on thingiverse.
The purpose is to blow the smoke away to protect the lens, but it would be nice to hear that spared a pass for someone.
This should fit all short focal length lasers, with 40mm body and 18mm diameter of this"brass thing" around lens.
mine is like this: https://www.aliexpress.com/item/33033806861.html
Used hot glue gun to attach fan and double-sided sticky tape to attach to the laser.
it's holding good. maybe will add some more sophisticated mounting later.
Maybe will redo this with some more attention and respect to air dynamics, someday.
Please note that using this renders your focus finding column useless, you need new one.
