About this 3D model

This is a simple case for a 2mm mushroom head push button that I designed for an upcoming project. It is meant to be screwed onto a surface and features four mounting holes on the bottom. You can find those push buttons on AliExpress by searching for "push button mushroom".You will find e.g. this one:https://de.aliexpress.com/item/4000031677760.html As always I have attached the FreeCAD file, so feel free to modify the design.
