Part 3: 3D Printed Repair Put to the Test – Will It Work?

3D Printed Repair Put to the Test – Will It Work?
In this final part of the series, I take the custom CAD model we designed in Onshape and bring it to life using a 3D printer. This broken vacuum sealer lever needed a precise and durable replacement — but will the printed part actually work under real use?

My 3D Printer:

In this video, you'll see:

How I prepare the part for 3D printing (slicer settings, filament choice, supports)

Real-world installation and testing of the replacement part

Whether the design holds up — or fails

* This is a practical example of going from idea to working fix using CAD and 3D printing — perfect for engineers, makers, and DIYers.
