How to print spiral(spring) static? I have designed this model:

My goal is to make it static, no vulnarable to shakes.
The pitch is 40 mm with 4 revolutions. The dimensions of the 'wire' are 5x5 mm.
Which settings for printing should I use to archieve hardness? I plan to make the wire 5x10 mm height, 4 walls, 0.28 layer height, 0.5 nozzle size. PLA. I don't know if this is overkill or it will be useless.
I hope you can give me suggestions about printing settings and model dimensions.
I know that's spring design, which is made to be springy but I need it for other use.
Second design. Less springy, but not by much. My last hope is to print it horizontaly.
If you want an helicoidal object which acts relatively rigid, you should pick a plastic which is very rigid to begin with. In the case of 3D printing, probably PLA is the best choice. Make it as thick as you can in all the directions where you have no constraints.
Still, it's an object which will be hardly printable without dissolving support material. You need a two material 3D printer if you want to get good results.
