Helpful video! I didn’t really know what those tools were called. I got a three pack of them from Harbor Freight (different socket sizes) which work just fine for me.
Do they sell these without the ratchet mechanism? If so, what are they called? Finger wrenches? I tried making one on my 3D printer (which is also what I need it for) using carbon fiber filament but even that wasn’t sturdy enough. Even a small amount of torque twisted the head clean off.
