Firstly, In Tale of Years it says of the jewel-smiths that (paraphrased): they reach the height of their power.

Celebrimbor had reached the height of his skill. Why would he try and make more rings if all his thought went into the 3 elvish rings?

... and even if Celebrimbor wanted to make more rings (which is illogical) when would he have had the time and effort? Sauron, realising the elves perceived him through the One, used Plan B: to take the rings by force. This was only about a year or 2 later.
