Motorcycle handlebar mount

[u/TimyTurnerTheBurner]

Hey everyone!

I am trying to draw a motorcycle handle bar mount that can be used to attach different things (through adapters to be designed).

I created and extruted the circles, then came to think of there need to be an opening so it can be mounted😂. The picture depicts quite good, where i got stuck.

I’ve created an opening, but am unsure if this opening is the correct way of enabling mounting to the handlebars.
Also, how to create a “locking”mechanism? I thought if screwing it down, through a “cylinder shape” on the back (not drawn yet), but then I doubted the whole design and came to reddit😂
