Snap-on relay case

I made this Case to fit my 4 way Relay.
It is the same height as the raspberry pi case I downloaded from here

That I printed that with the Octoprint cover found

It is not an remix but the idea is the same but the Snap-on works different

This is an adjusted version because the one I printed did not fit correctly. hope it is good now.
I printed it without supports just with the top\bottom site on the print-plate

This is the first thing that I share
