I found the original lock for the mounts a little loose so I tried this one: https://www.thingiverse.com/thing:3375629

But I think it works better when bent in the other direction, so I remixed it.
Print on its side.

It might be a tight fit but just insert it and move it up and down the rail a bit to 'sand it down',
