DIY Cab Merger Box

I've seen the question many time on how to connect multiple cabs to a one speaker jack amp.
I wanted to use 2 cabs for my Class 5 head and the amp only has one 8 ohm, and one 16 ohm speaker jack.
The usual recommendation is a Palmer Cab Merger.

These things are now $56 on Ambazon, so time for a DIY.
Got these parts instead for about half the cost.

Using this simple wiring diagram, I made the box with 6 jacks and separate parallel and serial connections.

It's a tight fit in the mini pedal case, so you may want to get a larger box.

Note: the the serial side needs isolation washers on the speaker jacks or the tip to sleeve connection shorts out on the metal box.
A plastic box or plastic sleeve jacks would also work.
Some peel & stick labels and good to go.

That’s fantastic!
I’m far too lazy to DIY that one…I’d probably make a little mistake that would end up costing me..
I‘ve been using one of these…

Those are nice too, but even pricier than the Palmer.
Line level out would be a nice feature.
You could feed another amp for a wet/dry or just stereo with a second amp tone - I've got 4 amps in my living room and still never tried that.
 
I’ve somehow acquired more heads than speaker cabs. I’ve got my eye on this widget (ain’t cheap). I could really use a 8 amp to 4 cab selector.
