We’ve owned a 3D printer for many years, and just like the internet, I am constantly delighted by it. This is a quick example of a practical use.

Problem

I had a lot of these PCBs to modify and I needed to hold the blue screw connectors in place while soldering them. Soldering each pin takes some time because of the mass of metal attached. It was difficult to hold them in place because of the secondary PCB fitted to the main one. Time for a jig. Luckily, the proximity of the edge of the PCB made this practical.

Fusion

I am by no means a designer or CAD operator but I learnt Fusion (360) using YouTube videos before Covid and used the extra time at home during Covid to practice turning concepts into reality. A little bit of measuring, 10 simple lines and this part is extruded. I sent it to the printer on “Fast” mode and continued soldering parts to the boards.

Solution

Once the print was finished (less than 5 minutes), I tried it and it fitted nicely. This is quite rare - usually I need a few iterations to get things exactly right but this is a very simple design. The remaining boards were very easily finished.

Make Your Own Tools

3D printers are so versatile but using one to make your own tools is the best. So much time can be saved. I look forward to the day when I can 3D print metal at home.
