Smart Tool Holder - Small Glue Holder

Couldn't find a use for the round raised area next to the allen keys and wanted somewhere to put my glue so i made this.

Insert the plug from underneath, there's a ridge on it so it doesn't push all the way though. Push the cup bit down over the top of it. It should friction fit but if not either scale it, file it or glue it (mine fit with gentle whack with a small rubber hammer)

Preferred it friction fit so I can pull it off and replace the cup with a bigger cup somehow if I start using t
