Fasteners for surface-mounted socket block

A fastener for a surface-mounted outlets block. I mounted one, with sockets individually controlled by relays, with a couple of the fasteners on my aquarium stand.

The parts fasten the block to the wall very tightly, I even doubt if I can unfasten it when needed :-) though I did it successfully, on my lap.

Simply snap both latches at the very end, when both are already screwed to the wall and the socket block is already tucked into both.

1. Added a next version of the openscad script: "socket_block_fastener2.scad" and a fastener model for another my outlets block has a different profile.
To print the first model using the new script You need to change the array "scales" to [1, 1, 1, 1] and the variable "length" to 41.
