/diy/ - Do It Yourself

I asked this in /QTDDTOT/ but you lads helped me in the past and one option is related to linear actuators which is part of /3dpg/ I guess.

So I need a platform to press up vertically, and I don't know how to go about it. The force "F" (which isn't all that much) is needed to activate.
I have 2 ways to solve it. Either a linear actuator built from a threaded rod and a platform pressing up. This is slightly harder to build I think.
Would I go with a threaded rod? Cost is my main problem. Any other linear actuator I found costs way too much. I don't care about accuracy.
Other alternative is a direct servo and a angled 3d printed piece. It won't apply the force vertically (at an angle so some of the force is not going to be applied but again, not the problem). This would be easier I think, but maybe it would break?

Any other ideas?
