Vacuum Hose Adapter
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
This file is designed to create adapters to connect shop or household vacuum hoses of any diameter with tools with any size round tool ports.
You can use Customizer to specify the inside or outside diameter of each end as well as the length of each segment. The adapter has a grip ring added above the top of the large section to provide a grip to pull it off the hose/tool. (If overall length is critical for you, note that the grip ring and its taper add 2 x Wall Thickness to the total height of the object.) You can specify an optional internal ring at the lower end of the small section to keep a tool from being sucked into the adapter.
May 2022 -- Updated Version R 1 allows you do specify any dimension in 0.1 mm increments
January 2024 -- Updated Version R 2 added an input variable to specify the size of the projection of the ring on the large end. A negative value cuts a groove into the tube.
All dimensions are entered in mm. (Note: Customizer seems NOT to like trailing zeros in decimal dimensions; so enter dimensions as 10.1 or 10.13, NOT 10.10 or 10.130)
Thingiverse Customizer sometimes seems to refuse to run. (It probably takes a lot of computer resources to Customize files for everyone in the world.) A workaround is to download the OpenSCAD application and process the .scad file on your own machine. I have posted a brief guide. http://bit.ly/openscad-at-home
