This Project was made for a friend, and there the sizes seams to fit well. So here the disclaimer: I did not check the size for myself, please use the FreeCAD file if you need so!
Here I give you an STL to repair a may broken slider from your Hasbro Connect-4 table game.
Also, you will find the FreeCAD FCStd file if you want to change something, feel free to do so ;-) (this was done by the FreeCAD LinkeStage3 branch from Realthunder)
