Looking for button cap

Hi,

I have a few of those buttons: https://www.sparkfun.com/products/11994

I was wondering if it’s possible to put a cap over them? I’d like to be able to fit a square cap on top. I can’t find any specific item that could work. A quick search seems to indicate that these buttons are model number “PBS 110” But I can’t find anything that would fit on them.

I haven’t seen any square-head button caps available out-right; your best bet might be to be 3D print something based on these specs here http://cdn.sparkfun.com/datasheets/Comp … -11992.pdf and glue a square cap onto the round one
