Soldering aid, third hand. Magnets instead of joints.

thingiverse

This little helper makes soldering wires together a breeze. Unlike the joints used in many third-hand designs, this device relies on magnets that can be moved and rotated freely. With no direct contact between the magnet and iron plate, three layers of filament act as a buffer, providing low static friction and precise positioning control. The flat design allows users to rest their hand on the table while soldering, eliminating bending and strain. This tool is surprisingly easy and fast to use. Print with PLA at 0.2 mm layer height. When preparing the base part, adjust your slicer so that the distance between magnet and iron plate remains under 0.6 mm (three layers at 0.2 mm). The recess for the magnet in the base measures 17 mm in diameter and 4.9 mm in height. The alligator cap is specifically designed for a Hirschmann AGF 30 alligator clip. All countersunk screws are M3 x 10 mm long. To assemble this device, you will need two base parts, two magnets, two alligator parts, six screws, and an iron plate.
