I liked 3dfernando's Helping Hands, but I wanted a better way to hold them on to my really thin table and also more flexibility in being able to fix them to any other thing, so I thought they would remix really well with my Mini screw clamp.

I've redesigned the clamp to have a sturdier, stronger screw. This model still prints really well in place, though it's dependent on really tight tolerances. If there's interest I wouldn't mind uploading a looser clamp, though 3dfernando's original ball socket has a pretty tight fit anyway.

PLA is doable, but i don't really recommend it. PETG works wonderfully well for these parts.
I've uploaded a thin version of the clamp (10mm), ideal for thin glass-top tables (like mine) or other supports, and a large version (20mm) that should cover something else. Over that, you're better off with a U-clamp like the original.

These files are untouched from the originals:

• ball_socket.stl
• Table_Clamp_Ball_Joint.stl
• Alligator_Clip_Receptacle.stl

Just insert your regular alligator clips with an M2 screw of your choice (6mm or shorter). I used M3's, but had to make the holes slightly bigger with a drill.
