Filament Reel Roller for Prusa i3 Steel

thingiverse

This is a set of filament reel rollers specifically designed for use with a Prusa i3 steel printer. The roller can accommodate reels with diameters starting at 200 mm and extending upwards. A pair of inexpensive 608ZZ bearings serves as the actual roller components. Just four printable parts are required: the left-hand frame, right-hand frame, and two internal frames. Counter-sunk M3 bolts are used to securely clamp the roller onto the top of the printer's frame. To allow for full upward movement of the X carriage, a portion of the front frame is carefully cut away. Print Settings: Printer: Prusa i3 Steel 200 x 300 mm bed Rafts: No Supports: No Resolution: 0.2 mm Infill: 50% Notes: I successfully printed mine in ABS plastic, placing each part's flat faces on the platen and using a 5-layer horizontal and vertical wall structure with 50% infill.
