Flexible segmented vacuum hose 40mm (fits DN40 pipes) for ShopVac

<p>This was inspired by Marius Hornberger who made something similar for 75mm and 100mm pipes which was way to big for me. So I ended up in making my own design using tinkercad.</p><p>This design has 40mm tubes on both ends, the longer one is intended to fit into a DN40 pipe, the shorter end is your actual nozzle.&nbsp;<br>If required you can build your own additional nozzle as needed to fit to the 40mm diameter, length is 25mm (a conical design 39.5/40.5mm may be a good idea), a nozzle for drilling is also included to download here.</p><p>With 5 elements you get an angle of nearly 90°, so with 10 to 12 elements you have a wide range of flexibility.</p><p>I printed it using PLA with 100% infill at 0.2mm layer height. It has a tight fit in the beginning, so it needs some initial movements or even sanding (just sand the smaller male part slightly) to make it work - but this way it won't get to loose.<br>PETG might work better due to its higher flexibility.&nbsp;</p><p>Print orientation as it comes from the STL files.</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p>
