If You're Equipped with Self-Tappers, There's No Need for Additional Tools
Self-tapping screws have gained popularity in the world of 3D printing, offering a straightforward and cost-effective solution for connecting 3D prints. These screws, designed to cut their own thread into soft materials, can be used for reliable coupling with 3D prints, making assembly a breeze.
The technique for self-tapping connections in 3D prints does not require additional tools or processes beyond those for construction. This means that, for a 3mm self-tapper, for example, you can follow the same procedures you would for a traditional screw. Align the holes and screw the self-tapper into them.
It's important to note that overtightening the screw can risk stripping the thread. To avoid this, ensure you tighten the screw to the recommended torque.
Many common screws, such as wood screws and those used for aluminum sheet, are self-tappers. For 3D printing work, self-tapping screws are often preferred over machine screws like M3 bolts.
In contrast to self-tapping screws, threaded inserts are machined brass pieces designed for 3D printed parts, heat-set into a printed hole. While they serve a similar purpose, self-tapping screws offer a time-saving advantage as they do not require additional tools or processes.
A simple example for a 3mm self-tapper in OpenSCAD is provided, offering a practical starting point for those interested in incorporating this technique into their 3D printing projects.
One of the benefits of using self-tapping screws is their versatility. They can be used for mounting Raspberry Pi LCD screens, for example, simplifying the assembly process significantly.
The technique for self-tapping connections in 3D prints has been found to be a valuable time saver. By designing a self-tapping connection in a 3D print, you place a suitable hole for the screw thread on the upper side, and a smaller hole on the lower side for the thread to bite into.
While the origin of the design for the self-tapping connection in a 3D print file remains unclear, sharing this technique is hoped to provide a useful tool in the reader's 3D printing work.
It's worth mentioning that the adoption of self-tapping screws in 3D printing is not universally accepted. Some prefer traditional methods, making it a matter of personal preference and method.
Regardless of your approach, the use of self-tapping screws can make the assembly of a 3D printed structure easy, offering a practical solution for connecting 3D prints in a straightforward manner.
