I've searched in the internet about a solution, but I didn't find a satisfied one, therefore I opened this new topic.
I use Printhat from Wreck labs and Octoprint to build a Ultimaker Clone.
With my original Ultimaker I have the possibility to print offline via SD Card. I loved this feature because sometimes I carried my printer away in place where I didn't have internet or for example in a classroom, where for 3D exercise more students want to print different things at the printer but don't have access to a global wlan connection.
Now I want to have this solution with my actual setup.
Is there a way to install a Hotspot on my octoprinter so for example (like a hotspot with the smartphone) every student in a classroom can connect with the PC or smartphone to the printer and send prints to Octoprint or check if the actual print is running well?
Without having a router installed or the need of additional hardware?
