As I mentioned in a previous post, there is no mains terminal cover on the power supply and I said that I’d 3D print one.
As luck would have it, somebody else had already done just that and posted their design on Thingiverse.

So I loaded it onto my 3D printer and set it going.  My 3D printer is quite old and not very fast, so it took nearly 2 hours to print, but you can basically set it going and forget about it.

The resulting print was ok.  Once I’d cleaned off the supports and the odd stringy bit of filament, it was good to go.

I might make a modified version that has holes in the top to give access to the low-voltage terminals, but that’s not really a priority.  I doubt that I’ll be removing the connections very often.
