Screw Jack Lift Platform

Designed to regulate the focal lenght of a microscope, so i dont know the max waight it can lift. This design can travel 12 mm up and down.

Some extra components that you would need to asemble this particular setup:

1) 4 x M3 screw

2) Metallic inserts for M3 screw ( https://es.aliexpress.com/item/4001307582528.html?spm=a2g0o.productlist.0.0.3b0f15b9NTzbNr&algo_pvid=b55de4d6-8cf6-46cb-86df-a4780374ee2e&algo_exp_id=b55de4d6-8cf6-46cb-86df-a4780374ee2e-21 )
