Nice, I have an Creality CR10, kind of the big brother of the Ender 3, bigger build size, taller etc. I think anything from Creality is going to be a good bet at the moment.
I also use Tinkercad, it's really easy to get started and you can easily load in files you find online and edit them to get started.
Seems like it should be fairly simple to model something like this...
