I am trying to create a 3D printing cost calculator website, that takes some input data and an stl file and renders the model + outputs costs associated with the printing.
The rendering is made with Madeleine.js and the slicing with CuraEngine. The only thing that is missing is to pass the uploaded STL file to the php code that runs CuraEngine (at the moment I am slicing a test file bitcoin_coin_flowalistik.stl on my local server). I can't find where Madeleine stores the STL files and how can I pass that information to the shell_exec php function towards the end of my file. Thanks.

<h1>3D Printing Price Cost Calculator Tool</h1>
<p>This tool is designed to help calculate the "actual" cost and profit when selling a 3D Printed part.<br>
To use the 3D Printing Calculator upload your STL file, enter the values below and click submit. The calculator will slice your file and estimate the values needed to calculate the cost of the print.<br>
To fine tune and adjust the data below click on the setting button and adjust as needed.</p>
