*.step file and FreeCAD file included, so you can modify the model if you want.The FreeCAD file contains a parameters' spreadsheet, so you can easily modify that you want.The FreeCAD file also contains an original version of the model, but that version is unfinished.
If you want more strenght print it on side with supports, or use stronger infill patterns when printing. (e.g. cubic, quarter cubic, octet ect.)I printed it with 60% infill, I suggest you the same or higher value.
