Yeah, that's pretty much it, "Transformer Chassis Seat". It's super secure as is (I can pick up entire chassis by grabbing the donut) no need to redesign for this amp. Happy to share the STL file for others to try. The pipe strap was $2/ea (I bought a 12 pack). So, under $4 total cost for app the parts: M4 bolts/nuts, fender washers, 42gr TPU material, and the strap. Of course, you need access to a 3D printer that has direct drive for TPU prints.

The pipe strap is an excellent idea! Sadly I don't have a 3D printer. I might figure something else out!
No "preorder" option as far as I'm aware. However, you can sign up for the email alert ("Notify me when available") for when it's back in stock at the store.

My backup plan for mounting the transformer vertically was to use a Simpson Tie (L-bracket) from a big box hardware store, and just drill some holes to mount to chassis perforated plate and the bolt that comes with the transformer. Others have recommended that as an affordable diy option. The 3D printed idea just seemed a little cleaner, easier for me to do, a fun design challenge, and slightly less expensive.
There's always a 3D printer house that will do it pretty cheap, or you find a Makerspace near where you live, ask your buddies buddies if they have a 3D printer (there are pretty common for "diy-ers" to have), or PM me and I'll hook ya up.

That’s a good idea and will do. 
I’m not 100% in love with this arrangement and should come up with something a little better, including insulating all the legs. The safety cap might be better installed on the PEM, which would make the terminal block wiring even simpler… will think about it a bit.

You don’t really need a 3D printer, all you need is the 3D cad STL file (if the designer doesn’t mind sharing) and then simply send it to JLCPCB, they do very good work, are fast, not expensive and lots of materials to choose from.
Donuts are usually having lesser emanating field along center axis
