Customizable Dustbuster[tm] attachment

prusaprinters

<p>A customizable Dustbuster[tm] attachment, with varying tip length and diameter. I made it for getting into really small spaces, but it also works to make other sizes. Could be combined with <a href="https://www.thingiverse.com/thing:1571860">http://www.thingiverse.com/thing:1571860</a> to make even more variations.</p> <p>It might need a slightly better shape to have a perfect seal, though probably some tape on the outside would help.</p> <p>I designed this by first scanning the bottom of an existing attachment, then bringing that into OpenSCAD as an image. After a few false starts, I found the right way to make it well-rounded: make a polygon that roughly fits the inside of the scan, using offset() to make it fit the outside as closely as possible.</p>
