My Printer are not in the "Printer Model" list

I am using AstroBox Touch and would like to enter my printers.
But they are not in the “Printer Model” list.
Can someone help me there?
I have the following 3D printers:

Geeetech Me Creator 2

Geeetech Duplicator 5

FelixPrinters Felix TEC 4.1

To AstroPrint: Can you also enter the printers?

Bye Torsten
