Description
Prompted by a complaint online that their students were, in their curiosity, poking the Robox eject button and ruining demonstrations, this is a quick hack-up to protect against that.
This fits into standard Robox spools and just covers the button, and is easily removable if you actually need to get at it in extremis.
