Just a small Bolt Hex head redesign

Because I had no nice Bolt-knob for using with https://makerworld.com/en/models/439137#profileId-344874 I just redesigned and flat cuttet this nice model https://makerworld.com/de/models/549921#profileId-468811 to use it with M4 Hexagon socket pan head and other M4 screws. Maybe you have to fix the screw with superglue.
