Simple key holder, with a minimal custom brim provided for easy printing. Maxing out perimeters (no in-fill) is a good idea for strength and proper flexing. I used PLA, but PETG is probably more robust. Clamp pressure might also be lower with PETG, let me know if you try it.
The default model has a gap of 6mm, so it will be loose with only 3 keys, and should work for up to 6 keys. More than 6 keys might be too tight. You could probably stretch the model in your slicer a bit for fewer or more keys. Or, you can change the clamp_gap_max variable to 2 * (number_of_keys - 1) (for standard 2mm keys) in the VarSet in FreeCAD. Many other controls are available in the FreeCAD file like length, height, curvature, and wall thickness.
