Designing and 3D Printing a Replacement Parts with FreeCAD

In this blog post, we will delve into the intriguing process of designing and 3D printing a replacement part using FreeCAD. The primary focus will be on fixing a broken locking nut for a retracting pole stand for a Dremel tool. We will outline the steps involved in creating a new locking nut by leveraging FreeCAD software and a 3D printer. Let's dive into this innovative and practical DIY project!

Understanding the Problem: Broken Locking Nut

The initial challenge faced by our creator was a broken locking nut on a retracting pole stand designed to hold a Dremel. This crucial component needed a replacement to restore the functionality of the stand.

Leveraging FreeCAD for Designing

The first step in the process was to utilize FreeCAD, a powerful open-source parametric 3D modeler, to design the replacement locking nut. The creator imported an image of the part and meticulously scaled it to the correct dimensions using the interactive scaling feature in FreeCAD.

Tracing the Design

The creator outlined the profile of the locking nut using the Part Design Workbench, creating a sketch for the revolve operation. By tracing the image, the creator accurately captured the necessary dimensions and geometry required for the new part.

Adding Details: Creating the Thread

To replicate the intricate thread detail on the locking nut, the creator measured the thread pitch to ensure accuracy. By tracing a single tooth of the thread and employing a subtractive helix operation, the thread feature was incorporated into the design.

Enhancing Grip: Adding Ridges

In order to improve the functionality of the locking nut, the creator added ridges along the cylindrical part. These ridges provide better grip and usability, akin to the original design of the component.

3D Printing the Replacement Part

With the design ready, the next phase involved 3D printing the replacement locking nut. The creator successfully translated the digital design into a physical part that closely resembled the original component.

Conclusion: Empowering DIY Solutions

This DIY project exemplifies the power of combining modern tools like FreeCAD and 3D printing to solve everyday problems. By showcasing the process of designing and producing a replacement part, this project inspires creativity and innovation in addressing mechanical issues.
