Wanhao Extruder plate for Ninjaflex

I was able to print tpu with no many issues, but Ninjaflex was always a problem.
so i decided to disassembled the plate every time the filament got stuck and always found that the filament was making a loop or exiting by the little space between the wheel and the plate. so i add a little slip that fill that space in the wheel, without affecting it and that help to no just print Ninjaflex with success, but at decent speed of 50mm/sec so far.

I recommend to use a small layer size, about 0.1
