The file 'Mobile Phone Hook Holder 3D Printer Model' is (stl) file type, size is 6.2MB.
Depending on your printing speed you may check adhesion layer setup on Cura.
Having some issues on first layer with 150mm/s, but with 100mm/s works pretty smooth.
Also I've tried with 0.6 nozzle and it looks pretty good.
