I made a filament holder to get this off the desk. It mounts on top of the printer frame. I made it for the ANet A6 but it would probably fit the A8 as well. The gap on the stand is 8mm. It uses the threaded rod, nuts and washers that comes with the A6 to hold the filament. It also uses 2 0608 bearings for completely smooth filament movement. There is also a guide built into the base. It is made to fit a wide variety of spools.
Supports are only needed for the curved base . Everything else does not need supports.
