Magnetic PCB Holder / 3rd Hand

Hi,

I needed a third hand / PCB holder for soldering one of my upcoming little electronics projects. I liked the concepts of the linked designs from vtjballeng and Hassla, but I was missing the specific parts they used. So I designed this remix around components I already had lying around.

Size: Holder body = 40 mm x 40 mm (diameter x height)
Included are two types of screw-caps, one groved and one knurled.

My print settings: 

• Nozzle: 0.4 mm 

• Layer Height: 0.2 mm

• Walls: 4

• Infill: 15% gyroid

• Material: rPLA

• Supports: no

Materials:

• 1x M8 hex nut

• 1x M8x30 screw

• 3x magnets 8 mm x 2,6 mm

If you like my PCB holder design but need different dimensions for the magnets or the hex screw, just ask nicely. If I find the time, I can add another version here.

Happy printing!

I used concepts and elements from both designs and combined them into a new model that I built from the ground up. For example, I used the hex‑head screw and nut from one design, and the grooved cap from the other.
