Ostat Hose & Pipe Adapter Generators

About this generator

Ostat Hose & Pipe Adapter Generators is a free browser tool that designs adapters for vacuum hoses, dust collection pipes and power tool ports that do not quite match. It comes from ostat, the maker behind Gridfinity Extended, and runs the open source OpenSCAD script in the page, so there is nothing to install and no account to make. The site has three generators: a basic hose adapter, a full hose adapter and a funnel maker.

On the basic page you set the diameter, length and taper of each end, say whether you measured inside or outside, and add a hose stop or barbs. The middle section can taper for joining hoses, lie flat for fixing to a tool or machine, or bend at an angle you choose. The full page adds magnetic and screw flanges, square or round nozzles, threads (a beta option as of September 2026), up to six copies of the second end for splitters, a flat base to help print bends, and ready shapes for ports such as Dyson, Festool Cleantec, Makita, Bosch and DeWalt DW735x. The funnel page covers opening size, spout angle and tip diameter.

The preview redraws after each change, settings live in the URL for bookmarking or sharing, and Save STL downloads the file. It suits woodworkers and shop-vac owners with calipers and a hose that will not fit.
