Solder helping hands are an awesome aid in the workshop.
Helping hand arms need to be flexible and precise so you can easily position objects.
These 3D printed helping hands are easily configurable to have more arms or be longer
with the round base focusing all the arms on the central work area.

Comes with two sizes of crocodile clip connector parts. These have an internal diameter of 4.5mm and 5.5mm to glue in your clips. I bought my clips at Aliexpress.

More details and tips on how to make on YouTube.

Print with no supports.
I printed with 0.2mm layer height in PLA.
Use 4 layers on the walls:
Prusaslicer - Vertical Shells -> Perimeters = 4
Cura - Wall Line Count = 4
Infill was 20% but as its so small it's all walls.

Recommend having at least 5 pieces in each arm (includes the crocodile clip holder).

Move the arms around after first clipping together to loosen them up at bit.
