CAD + FDM Printing

Custom cooktop duct adapter for a client fit-up problem.

The supplied bracket and ducting did not suit the installation, so a custom adapter was modelled and printed to bridge the required rectangular and round profiles.

The problem

A client needed a duct transition that was not available off the shelf for their cooktop setup. The job needed practical geometry, not decorative modelling.

Quality3Ds created a CAD model around the required fit and produced a large printed adapter so the client had a part made for the actual space rather than forcing the installation to suit a generic bracket.

Project scope

Custom CAD, rectangular-to-round duct geometry, print-orientation planning, and a large-format functional FDM print.

Final installation and compliance checks remain with the owner or relevant trade.

Design and printed result

This project shows the value of local CAD support: the printed part is based on the customer problem, not a standard catalogue shape.

Why it matters

Made for the installation

CAD can solve awkward fit-up problems where standard parts do not match the real geometry.

Fast local turnaround

Local design and printing keeps iteration practical when a job needs a part quickly.

Useful beyond one-offs

Once modelled, similar adapters can be adjusted, reprinted, or refined for later installs.
