Clamp for cyclists

Clamp for cyclists with an arrow and a smiley face

I have been thinking about this model for a long time, I think it is suitable for the theme of the competition.
I myself am a big fan of cycling, there are more and more cars on the roads and it is no longer safe, so I would like this model to remind drivers of road safety rules.
I know that we all have to be disciplined in order to feel safe.

The model consists of an opening clamp, a connecting arm, two knobs for an hex M6x15mm screw with hex nut and an arrow with a smiley face.
You connect the clamp with an Allen screw with a cylindrical head M4x12mm

Some of the holes are covered in order to print the bridges well, drill the hole with a 6mm drill bit

The clamp is for seat tubes with a diameter of 31.6 mm, I also added an adapter for a diameter of 27.2 mm
