I was riding my bike today. I have a little round mirror on my left handlebar that is mostly blocked by my body.

And I thought. What I need is a periscope.

Yeah. A periscope.

I just have to figure out how to design it.

I know how to cut glass and dabbled in kaleidoscope making.

I can also do 3d modeling and 3d printing.

So honest opinions. Do any of you think the could legitimately work ?

It would be like a tube shape running the bar length. With a viewing window that would sit on top. And a capture mirror behind the seat facing backwards.

Might take a while to design this but I think it is possible.

I think you could make something that works, but it would be heavier than just having the mirror out a little further.
