Odd shaped "gasket" ring help
(OP)
I am designing a "gasket" ring for my company and I am having trouble finding a vendor to quote what I need. Unfortunately I can't disclose any major details but I will do my best in describing it.
It is approximately 0.29" in diamter, 0.01" thick ring. There are "notches" at certain locations around the ring allowing another circular ring to seat into those notches. This ring needs to be flexible yet hard (shore A 80 or 90 durometer silicone), to be able to hold open the said circular ring at a certain diameter. I am labeling it as a "gasket" solely for the fact that we are using o-ring and gasket manufacturers as our vendors of choice and it does not act as a sealing gasket.
If this information makes sense, can anyone point me into a direction for a vendor that does custom small silicone gasket or o-ring manufacturing with medical grade silicone?
Or maybe in another direction that may be of help in my situation?

Does anyone know any alternatives to creating a small silicone part with a complex shape?

I'm guessing your quantities are too small to be of interest to all vendors, in which case building a Teflon mold and pouring your own part might be a possibility. I'm not sure if the usual castable silicones can meet your hardness spec, but you can ask.

If it can be "two dimensional" then why not laser cut it?

It cannot be two dimensional but it could be a good starting point because it would be a whole lot easier to cut.
