Everything is ready to print and no need for additional supports.
The spool roller is pre-supported and the ring support will come right off after printing.
The author remixed this model.
I used SHaDoW6 Side mounted spool holder to create a side mounted spool holder with bearings for the K1 Max.
This model replaces the one center back screw with (M3*12) and the bottom right fan screw with (M3*14) for mounting.
You will also need 2 x 608 type bearings.
