Giá đỡ cho Hot Air Soldering Iron

Hi,

At work we use two rework soldering stations. One is a fully integrated model from ERSA, and the other is an infrared heating unit combined with a hot-air soldering iron (Weller WTHA 1).

The goal of this project was to reduce strain on the arms and hands during long soldering sessions. The result is a holder with a quick‑change mechanism for the soldering iron which, together with a microphone holder arm, acts as a stable yet freely movable support. Thanks to this system, the person soldering once again has both hands free to work on the PCBA instead of holding the soldering iron.

It has been in use for two months now, and the feedback has been very positive.

The pictures with the grey holder show the prototype version. I will add more pictures of the final version (black ESD material) in January.

Print Settings:

• Layer height: 0.25 mm (0.4 mm nozzle)

• Perimeters: 5

• Infill: 10% gyroid

• Solid layers: 3 top and 3 bottom

• Supports: yes, see pictures

• Print orientation: as shown in the pictures

• Material: ESD‑PEGT (all parts ~130 g)

Materials:

• 2× M4 nut

• 3× M4 nylock nut

• 3× M4 washer

• 2× M4×50 screw

• 1× M4×80 screw or threaded rod

As a holding arm, we use this microphone holder: Aokeo AK‑35.
I've included the STEP file of the whole contraption in case you want to use it
with a different soldering iron or holding arm, or if you want to make any other improvements.

Update 05.01.2026
- added new pictures of the final ESD variant

Happy printing!
