@Gabriel_Petrut @Elliott_Polk A Nexus 7 should handle it. But: I’ve got an Ainol Nove 7 Elf 2 with a price tag of £120. It shows my stl files pretty well (with this app: https://play.google.com/store/apps/details?id=com.dukedev.hdmodelviewer).
Would love, if I it could be used to controll a 3d printer.
