This simple bin can easily be attached to your multiboard using the multiconnect connector system. I would recommend to at least use 4 connectors, one for each edge.

Note the bin is using an optimised “quick change” version of the connector back which allows to remove it from the board without needing you to slide it all the way up. You just need to push it up 25mm (size of the multiboard grid). See bin back for details.

You may also use the STEP file to create your own variation of this. Just have fun with this.
