I want to create a slider with prices, Wodrpess website

I have a website on wordpress, Divi theme. I want to implement a sock price slider on my site. We currently have 9 models of socks in our range. For each model I want to implement a slider that will change the prices depending on the size of the order.

An example of a similar solution can be found here: https://sokke.love/, https://www.customysocks.de/.

I tried to create something similar on my own via the https://stylishcostcalculator.com plugin. However, I can’t use it because for an unclear reason I can’t change the currency from dollars to euros. I have contacted the plugin service, but they have not been able to solve the problem.

I am looking for a “lightweight” solution that will not seriously slow down my site. What is very important to me, I care about a slider that I can edit, duplicate etc myself.

I have attached what a example section with a slider will look like.
