The wheels have a diameter of 40mm and were crafted with FreeCAD(https://freecadweb.org) to fit to an axle of an electric motor.
Without any modification the wheel fits on an axle of 1.9mm diameter.
In order to garantee a perfect fit, a clamp was added.
If needed you can open and edit the .FCStd file with FreeCAD.
In case you do not want to edit the diameters you can use the .stl file, import it into your favorite slicer, and eventually print the wheel with your 3D-printer of joice (tested with PrusaSlicer on a MK3S+(https://www.prusa3d.com/product/original-prusa-i3-mk3s-3d-printer-3/)).
After printing, just push the wheel over the axle and tighten the clamp with an M3 screw (DIN 912) and nut.
To get more friction on a smooth surface you can cut a small slice of an old bicycle hose and slip it over the wheel.
