This print is a simple credit card holder.
The assembly used M3 screws and inserts.
Note that you can modify the model by reducing the size of holes from 4 to 3 mm in the main body part if you do not want to use insert (it should work as well, source files are provided in FreeCAD format)
if your car are too hard to be inserted, just use a lighter or heat gun to flatten the lateral adjustment pins of the main body part.
