Replacement Threaded Ring for Budget Soldering Irons (Customizable Fusion File Included)

This is a replacement threaded collar ring for low-cost soldering irons — specifically, the fragile plastic part that often breaks between the handle and the heating element (see highlighted area in the photo).
After mine snapped, I couldn’t find any spare parts online, so I designed and printed this fix myself.
It works great and snaps on like the original.

🔧 What’s included:

🧱 .STL file ready to print

✏ Fusion 360 .f3d file for easy editing
→ You can modify the thread diameter to match your soldering iron model.

✅ Features:

Same external shape and function as the original ring

Print-friendly geometry (no supports needed)

Internal thread customizable in Fusion

Fits many common soldering irons sold under different brand names

💡 Why this matters:
Cheap soldering irons often have non-replaceable plastic rings that snap under heat or pressure. This simple 3D-printed part lets you extend the life of your iron instead of throwing it away.
Even if your ring isn't broken yet, you might want to print a spare!

🖨 Recommended settings:

Material: PETG or ABS (for better heat resistance)

Layer height: 0.2 mm

Infill: 100% or 50% with walls ≥3

No supports needed

⚠ Note: Check the thread before printing. If it doesn't fit your soldering iron, you can easily adjust the thread in Fusion using the included .f3d file.
