Thanks for the comments Mark. I guess I was a bit generous with the silicone.
Most of the 6 point ATM cells I found mentioned the silicone blob to be the size of a dime, mine is around a 20c piece.
what I don't understand with the commercial ones is how the mirrors are secured without pinching at the sides, this one for example,

I'm guessing the side clips prevent the mirror falling off so there's no silicone at the floatation points.
I was trying to secure the mirror without side clips or having the primary support at the sides.
if I used smaller blobs, would the mirror be secure enough?
I went with the big square sections to get the contact area the size of a coin, this one's 25mm. I could use smaller ones and that would lower the profile.
But do you recommend lowering the profile to prevent lateral movement?
the mechanics of the 6 point actually prevent sideways movement and any movement would be more due to the elasticity of the silicone.
anyways, I will research more and redesign or might just get the one in the link above.
Thanks
