Unfortunately no, at least not that I can still find. It was really just a lap tray and I used industrial Velcro with adhesive on the back, along with an adhesive mousepad. The mouse holder is just from the box it came in.
The challenge was the lack of wireless for the single-handed hardware keyboard at the time, so a USB2BT module was needed, and those knobs I added at the top were for wrapping a wire from a tiny USB2.0 Hub for if I wanted to be wired.
Doing it again it would be 100% wireless with magnetic quick charge connectors on all the elements. (I got a million of them of different angles off Aliexpress and have them on all my travel items).
If you need banking apps, consider a cheap used/old Android phone with a VNC server on it, then noVNC pointed to that to get it on the web.
