About this 3D model

Having just bought my first 3D printer, I realized my first impression by printing the Dagoma horizontal roller. Not practical. For coils with a diameter of 200 mm of Chromatik, the filament relaxes and releases the blanks of the coil which can jam. Having two bearings that did not serve, I had the idea to design my own unwinder. Unwinder consisting of: - 2 bearing 608RS ext. 22 mm, axis. 8 mm ep. 7 mm - 4 rods diameter 8 mm length 91 mm - 2 printed hubs - 2 printed axis supports - 2 printed axes - 1 printed foot
