hi, this is new to me, so i don't know if printing something like this is possible, but i'm sure you can have a look and tell me, see the crude presentation i attached. what i need, basically, is to design:
1) a plastic spring, about 3cm long, that can expand to about double that without breaking or losing elasticity.
2) at both ends, i need a contraption which is kind of like an electrical clip - this is where it gets tricky, as this is pretty small, say up to 4mm on the outside with a screw channel of up to say 1mm.
3) the screw itself can also be plastic and printed, or i can use watch screws, whatever the recommendation
would be happy to hear advice and planning/printing offers
