HeatSync - The Ultimate Heat Insert Press

“This has been a long time coming and now it's finally here, the upgraded version of HeatSync! I make these models in my free time so if you would like to support me, follow Thinkable on Patreon, leave a boost, and follow me on YouTube! Thank you all for the support! Let's build a better future together!

I make these models for free, so thanks for supporting my designs!

Back Story of the HeatSync Project:

Around 2022 when I started doing 3d printing I learned about different ways you could attach parts together using screws. Metal threaded heat inserts I found are amazing for this and so I bought a cheap soldering iron, press, and tips from amazon. The idea was that the iron in the press stayed in place and I could just press it down into the part to melt the insert into the part, simple and easy right? NO. That thing was a POS. It was wobbly and the ergonomics were hurting my arms after doing hundreds of inserts at a time. I also started thinking about using different kinds of platforms (jigs) for parts with similar heights/shapes. I saw that a power drill press had the exact type of mechanism I wanted (later adapted for HeatSync) and so I simply made an adapter for the soldering iron to go in. As time went on, I kept wanting to use my own custom jigs for the parts that I make all the time. The main problem was attaching/aligning the jigs to the base and easily removing them. At that time, there were NO similar options to what I wanted available online to download and print. So, like Thanos I said “I’ll do it myself”.

HeatSync is the culmination of the last few years of work I’ve put in to make my dream soldering iron press. And now YOU can make it too! Not only that, but I am also including the STEP files for developers so that you can easily modify and change this system to your needs/wants. I believe that you have to create the world you want to live in to make it a better place and this is one of my contributions. I hope you all enjoy and appreciate HeatSync and use it to make things you couldn’t make before. Happy printing everyone!

Printing/prep Guide:

3d Printer requirements:

You can use any printer including the A1 Mini :)

Filament:

PETG-HF : (heat resistant PETG material RECOMMENDED for the soldering iron holder pieces. They can get kind of warm with extended use)
PLA : Should be fine to be used for the rest of the parts. Tested to work great :)

Hardware:

You will need to supply a Soldering Iron, and Flat iron tips of your choice. Everything else you need is below.

HeatSync Hardware kit available on my Shop:https://thinkablecreations.etsy.com/listing/4464290389/heatsync-ultimate-heat-insert-press-for

This model uses mostly 3d printed parts with the main exception being the “300mm 2020 Metal Extrusion” bar that is the strong backbone of the system. I chose this bar to add strength as well as the ability to easily adjust the height to your needs. Some of the hardware is currently available on Bambu's Store, but I will be making a Hardware Kit available on my shop HERE which will have everything* you need to assemble the HeatSync. I will also include individual affiliate links to the items needed below. You will need to use your own Soldering Iron + Tips to complete the setup.

Hardware Type	Quantity Needed	USA Link (Affiliate)
M4x10mm Machine Head Screws	17	Amazon
M4x6x6mm Heat Set Inserts	17	Amazon
6.4x38x0.9mm Extension Spring with hook ends (¼"x1.5"x0.035")	1	Amazon
M4 Extrusion Nuts	7	Amazon
300mm 2020 Metal Extrusion Bar	1	Amazon
Soldering Iron	1	Amazon
Flat Tips for soldering iron	1	Amazon
M4x10 Thumb Screws (optional)	1-4	Amazon

Assembly Instructions:

Welcome to the complete guide for assembling HeatSync! Ideally it should take around 20-30 minutes to complete. Take your time and be sure to let me know if you have any questions or things you would want me to change or add to make it better.

Full List of (12) 3d printed parts:

(READ CAPTIONS IN PICS) First Install the (x13) M4 threaded inserts with you soldering iron

(be sure to not insert them too far, put them just far enough to not stick out of the parts)

***WARNING*** Keep the iron vertical and don't touch the sides when putting in the inserts on the pieces

2 inserts in the right side of the rack gear piece

1 insert on the LEFT side of the rack gear piece

(Optional) 4 inserts on the base - these are for future jig mounts (last step for the inserts)

Main Assembly:

(READ CAPTIONS)

**Step 1:** insert 3 screws into the back of the base

**Step 2a:** hold the extrusion nut while screwing in the screws

**Step 2b:**Make sure to screw in the nuts in the correct orientation! (no nut jokes please lol)

**Step 2c:** leave about 3-5mm of space for the bar to slide into

**Step 3:** Make sure the nuts are vertical

**Step 4:** insert the metal extrusion bar (tricky part)

**Step 6:** lay it flat on its back for the next step

**Step 7a:** insert screw into the main housing (1/2)

**Step 7b:** insert screws into the other side of the main housing (2/2)

**Step 8a:** attach the nuts and leave 3-5mm gap

**Step 8b:** (screws and nuts installed)

**Step 8c:** (screws and nuts installed)

**Step 9a:** slide the main mechanism onto the metal bar (CHECK ORIENTATION OF THE HOUSING)

**Step 9b:** (Correct orientation of the housing piece)

**Step 9c:** Again, make sure that the nuts are in the correct orientation!

**Step 10:** position the housing at the end of the metal bar and tighten the screws (you can adjust this later)

**Step 12:** install 2 screws and nuts into the handle (watch the orientation)

**Step 13:** slide the handle into the top of the slots on the metal bar

**Step 15a:** Connect the knob to the lever

**Step 16a:** insert 2 screws into the lever and screw them into the bottom of the shaft part

**Step 17:** Slide the Gear into the housing with the raised part on the left

**Step 18:** Insert the lever shaft into the Main housing (line up the middle of the gear to install)

**Step 19:** install the small end stop piece with a screw

**Step 20:** test the rotation of the lever (the gear should turn as well)

**Step 21:** Point the lever straight down before the next step

**Step 22a:** Get ready to install the Rack Gear Piece by pointing the Arrow UP

**Step 22b:** line up the rack gear to the groove on the main housing

**Step 22c:** (trickiest part) All in one motion, push up on the blue Rack Gear part, while also rotating the lever clockwise. You should hear a pop and the gears should now align. (more details in next picture)

**Step 22d:** top view of the rack gear installation (push up the entire time and it should pop into place)

**Step 23:** attach the small connector piece to the rack gear piece with a screw

**Step 24a:** time to install the spring…

**Step 24b:** Hook the spring into the blue hole first and then into the black hole. (needle nose pliers are useful here) I prefer the spring on the right, but left is also an option, or both if you have 2 springs. You choose what works best for you. :)

**Step 25:** Slide the holder piece onto your soldering iron (watch orientation)

**Step 26:** attach the front block to the soldering iron holder

**Step 27:** install 2 screws in the back of the soldering iron holder

**Step 28:** attach soldering iron into place

**Step 29:** install screw on the small connector piece

**Step 30:** install screw on the right of the front block

**Step 31:** tighten screw on the left side of the front block

**Step 32:** put cable through handle and in the hook

**Step 33:** Optional thumb screw for jig mounts

**ALL DONE** Pat yourself on the back, you are ready to go! Enjoy your HeatSync!
