@ellis-fortuna Hi there, you can get some modeling skills from below link:
https://www.tinkercad.com/learn/designs?collectionId=OSZ5W2BL1W5N51F&fbclid=IwAR3I8mAvr__hcAakVY4b23T5-ourM-0Z2hQ-Us2t4uMih2ixioDDT964TxI

And below are some modeling software:
Desktop Software:

• Blender
• SketchUp
• 3DMax
  Web-based Software:
• Tinkercad
  Mobile Apps:
• SketchUp (Mobile)
• Tinkercad (Mobile)

After connecting the printer with the APP and the wifi, you could go to “Me>Profile” on the APP and you will see a “+” option in the bottom left corner of the page.Then you could upload your own STL format models files to the app and to print it.

@SpoodyHollow Hi there, so sorry that our printers cannot use the AMS machines. If you want to change the color of the filament, you can go to "Prepare>Load/Unload filament" on the printer to change the filament color.
