UPDATED 18.10.2023: TamperMonkey script that allows you to download Thingiverse files without the pop-up and 5 second wait time.

@scoutman57 Thanks for the fix; it works for me.

Here's the updated script formatted properly for any one else needing it. I included @idle-user's change too.

    }
    downloadElement.onclick=function() {
        window.location.href = URL + '/zip'
    };
    downloadElement.innerHTML = '<div class="button button-primary">DOWNLOAD</div>'
};

They've changed the div name again, here's the new code that works:

function noBullshit() {
    'use strict';

    const downloadElement = document.querySelector('div.SidebarMenu__sideMenuTop--vJNxy > button');
    var URL = window.location.href;

    }
    downloadElement.onclick=function() {

    };
    downloadElement.innerHTML = '<div class="button button-primary">DOWNLOAD</div>'
};

@quantumfrost updated, thx ! <3

UPDATE 18.10.2023: Simplified the code: now the button is just replaced with a new one with completely different event listener, since the the updated pages now still displayed the modal and also triggered the download. Now the modal as well as the download countdown etc. is completely ignored !

Also added the selectors and the styling to the top of the userscript, so these are easier to update once Thingiverse changes these again. You can also now customize the text to your liking if you want !
