Vacuum Hose Adapters: 35 mm and 38 mm STL Models

This collection gathers 3D printing files for vacuum hose adapters, mostly around 35 mm and 38 mm diameters, plus reducers that bridge other sizes. It is useful when a hose, a shop vac and a power tool do not match out of the box and you need a part that fits your own combination. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Vacuum Hose Adapters: 35 mm and 38 mm STL Models»

The models fall into a few groups. Some are shaped for one vacuum brand or a specific tool port, others are plain reducers that step from one diameter to another, and a third group is parametric, so the inner and outer diameters can be set before export. Angled and slim versions appear as well, for tight corners or short runs where a straight connector would be awkward.

Before printing, read the author's page for the exact inner and outer diameters, the taper or clip geometry, and the wall thickness. Check whether the part is meant to slide over a hose end or into a port, since that decides the clearance you need. Look at the material and layer settings the author lists, and at photos of real prints, because a thin-walled adapter behaves differently from a solid one.

If the first search gives few results, try the diameter alone or the hose end size, then add terms such as reducer, step-down, shop vac or tool port. Searching by the tool type or by the connector style often surfaces files that a brand name would miss. Related topics worth checking are dust collection fittings, cyclone separators and sander port adapters.

FAQ

Preguntas frecuentes

How do I know which diameter I need?
Measure the outer diameter of the hose end and the inner diameter of the port it must enter, then compare both with the dimensions on the model page. Adapters are usually described by the sizes they join, not by a single number.
Can I adjust a model to a different size?
Parametric files let you change the diameters and often the length before exporting an STL. For fixed models, scaling in the slicer changes every dimension at once, so the fit may suffer.
What should I check about the connection type?
Some adapters push over a hose, others fit inside a port, and some use a clip or a threaded ring. The author's description and photos usually show which side goes where.
Which material works for these parts?
Rigid filaments hold a shape well for straight connectors, while flexible ones can help where the hose bends. The author's listed settings are the starting point.
