You can list multiple URLs separated by spaces.
Options can follow the URL and are:
'(high|medium|low) quality' -- sets the quality of the print. Default: medium
'xN' (e.g. x2) -- print more than one of a thing at once
'with supports' -- adds supports to the model, for complex overhangs. Default: disabled
'with raft' -- prints on a plastic raft, for models with little platform contact. Default: disabled
'xx% solid' -- changes how solid the object is on the inside. Default: 5%
'scale by X.Y' (e.g. 0.5) -- scale the size of the model by a factor
#{} 3d snapshot - takes a picture and tells you the locked status
#{} 3d unlock - unlocks the printer after you clean up
Only 1 print at a time is allowed, and you are required to tell
#{} after you've cleaned your print off.
The web frontend is at #{makeServer}, and
the most current log is always available at #{makeServer}/log"""
