Custom Pipe Reducer – Configure a 35 mm to 20 mm Adapter and 3D Print It

# Configure a Custom 35 mm to 20 mm Pipe Reducer Online

Many hoses, pipes, and technical connectors do not fit together perfectly. Standard reducer fittings are often unavailable, too short, or simply not suitable for special applications.

With our parametric pipe reducer configurator, you can create a custom 35 mm to 20 mm adapter in just a few seconds — without any CAD knowledge.

The finished reducer can then be downloaded as an STL file or ordered directly as a 3D print.

Typical Applications for Pipe Reducers

Conical hose adapters and pipe reducers are used in many technical environments:

- workshop vacuum systems

- dust extraction systems

- CNC extraction adapters

- machine connections

- ventilation systems

- aquarium setups

- laboratory equipment

- pool systems

- DIY projects

- technical repairs

- industrial custom solutions

Especially for uncommon dimensions or discontinued spare parts, a configurable reducer is often the fastest and most cost-effective solution.

# Example: 35 mm to 20 mm Pipe Adapter

This application example shows a conical pipe reducer with a large inner diameter of 35 mm and a small inner diameter of 20 mm.

The geometry is ideal for:

- hose reducers

- transition adapters

- vacuum adapters

- pipe connectors

- machine interfaces

The smooth conical shape creates a stable and efficient transition between both diameters.

# Advantages of a Parametric Pipe Reducer

Unlike standard off-the-shelf adapters, a parametric pipe reducer can be customized exactly for your application.

Benefits:

- precise diameters

- customizable cone lengths

- strong wall thickness

- optimized for 3D printing

- instant STL generation

- no CAD software required

- perfect for custom parts and spare parts

This makes it possible to reproduce rare adapters or discontinued components quickly and efficiently.

# Download the STL File or Order a 3D Print

After configuring the reducer, the model can be:

- downloaded directly as an STL file

- priced instantly online

- or ordered as a 3D print

The geometry is automatically checked and prepared for manufacturing.

# Why Custom Pipe Adapters Are Becoming More Important

Many manufacturers only provide limited adapter sizes or discontinue older spare parts. At the same time, workshops, industrial systems, and DIY projects constantly require custom transitions and connectors.

With parametric 3D models, custom pipe reducers and hose adapters can be generated within seconds — perfectly matching the required dimensions.

This saves time, reduces costs, and avoids complicated manual modifications.
