HeatSync - The Ultimate Heat Insert Press

The upgraded version of HeatSync is finally here! I create these models in my free time, so if you'd like to support my work, consider following Thinkable on Patreon and subscribing on YouTube. Thank you for all your support! Let's build a better future together!

About HeatSync

Around 2022, when I started 3D printing, I discovered threaded heat-set inserts and how useful they were for joining printed parts with screws.

I bought a cheap soldering iron, press, and tips from Amazon, thinking it would make installing inserts simple. Unfortunately, the press was wobbly, uncomfortable, and frustrating to use, especially when installing hundreds of inserts.

I wanted something better: a sturdy, ergonomic press with adjustable height and interchangeable platforms (jigs) for different printed parts.

After experimenting with drill press mechanisms and custom adapters, I began designing my own system.

HeatSync is the culmination of years of development to create my ideal heat insert press.

Now you can make one too!

I've also included the STEP files so makers can customize and improve the design for their own needs.

I believe 3D printing is a superpower, and sharing designs helps us all create better things.

Happy printing!

Printing Guide

Printer Requirements

HeatSync can be printed on most consumer 3D printers, including the Bambu Lab A1 Mini.

Recommended Filament

PETG (Recommended)

• Recommended for the soldering iron holder components
• Better heat resistance for parts exposed to warmth during extended operation
• Great for functional mechanical parts

PLA

• Tested and works well for most components
• Suitable for general structural parts

Hardware Requirements

HeatSync uses mostly 3D printed components, with a 300 mm 2020 aluminum extrusion serving as the main structural backbone.

The extrusion provides strength and makes it easy to adjust the press height.

Recommended: HeatSync Hardware Kit

The easiest way to build HeatSync is with the hardware kit available from my shop.

Buy the HeatSync Hardware Kit

The kit provides the necessary assembly hardware without requiring you to purchase large quantities of individual components.

Note: You will need to supply your own compatible soldering iron and flat heat insert tips.

Individual Hardware List

If you prefer to source the hardware yourself, here is the list of components required:

• 17x M4 x 10 mm machine screws
• 17x M4 x 6 x 6 mm brass heat-set inserts
• 1x Extension spring, 6.4 x 38 x 0.9 mm (1/4" x 1.5" x 0.035"), with hook ends
• 7x M4 extrusion nuts
• 1x 300 mm 2020 aluminum extrusion bar
• 1x Compatible soldering iron
• 1x Set of compatible flat heat insert tips
• 1-4x M4 x 10 mm thumb screws (optional)
