In this project we're building a rig for installing heat set inserts. Use 3D printed parts and hardware to build a solder rig with smooth linear roller action! Make perfectly straight inserts with precision using a tip for installing inserts.
When working with 3D printed parts, a press can help you install inserts. This holds a soldering iron vertically and allows you to press down, perfectly straight. The tip of the iron heats up the brass and softens the plastic. Pressing down pushes the insert into the part and once it cools down, it’s locked in place. This could be handy for folks doing a small production run or if you're looking for a tool to make this easier.
This rig makes installing inserts feel like pressing a hot knife through butter – The linear motion on this build feels smooth. This is definitely over engineered and we spent way too much time on it but we think folks will find it useful. The rig is modular and uses common hardware – The 3d printed parts can be remixed and modified to work with other components. There’s a learn guide for this project so folks can build their own.
Holding the iron straight seems simple enough and works fine most of the time but the conical shape of a regular soldering iron tip can catch the insert and accidentally pull it out while melting the plastic – And that can sometimes ruin parts.

Adafruit was founded in 2005 by MIT engineer, Limor "Ladyada" Fried. Her goal was to create the best place online for learning electronics and making the best designed products for makers of all ages and skill levels. Since then Adafruit has grown to over 25 employees in the heart of NYC. We've expanded our offerings to include tools, equipment and electronics that Limor personally selects, tests and approves before going in to the Adafruit store. We pride ourselves on having great prices, the best customer service, technical support and fast shipping. We hope we can assist you on your journey of learning - At Adafruit we celebrate engineering happiness!
