This is a set of helping hands designed to be entirely printable AND able to be extended when needed.

The all site around a tidied up version of the lockable joint I posted previously ( thingiverse.com/thing:2872 )

NOTE: sorry for the poor rendering I'm still getting used to using sketchup. It doesn't show but the arms should be fully pose-able.

I have improved the link itself, created a quick "Clamp" form of the link for holding PCBs, and created a base where 4 "arms" can be attached.

NOTE: Thanks go to Pandelume for the suggestion to replace the traditional 6 sided nut with a fluted thumb screw!


The base may seem rather small but if two arms are being used to hold the PCB then the other two can be extended and locked into position as legs to give the more stability.

The based is very simple at the moment as I didn't want to complicate an already experimental design unnecessarily

This is an experimental design (I have tried to make the thread large but dont know how well it will print), however If the design works (assuming I will have to make some mods) then I would like to design a range of different "Heads" other than the PCB clamp provided as part of this design.

I've included the SKP file for anyone interested - As a point of interest I had trouble with sketchup when calculating interceptions between models, and found that the software is much less likely to leave hidden holes in my designs if I work with the model at 10 to 100 times normal scale and then shrink it down for generating the STLs.

I posted a lockable ball and socket link yesterday as part of my design work leading up to this.
