Replacement Keycaps for Orbweaver

I have searched this forum and others looking for replacement keycaps. The posts on my keys have started to break. The Orbweaver is several years old so no warranty but willing to purchase new ones. It is one of the most comfortable gamepads I have found for people with large hands (can palm a basketball) and do not want to replace it.

Any suggestions?
I have sent in a ticket to support but also wanted to dual path by posting here.

Thanks in advance.
