Ultimate Lock-Down Filament Roller

thingiverse

I was fed up with filament spool rollers that made annoying noises, didn't fit any size of spool under 10Kg, required different parts for various spool sizes, had the spool fall off or over, and got dragged around. So I built this secure spool roller. It features a couple of acrylic tubes on skateboard bearings similar to other rollers. The addition of a threaded rod spinning on a bearing mounted to a z-axis enables locking in place any size spool. Pro-Tip: Lock the spool loose enough so it spins flat on the rollers. With the spool locked in place, there's no way it can fall over. There are holes to bolt the assembly to the table, so it won't go anywhere. 3D Printed Parts: - 1X : Top (no support) - 1X : Bottom (use support) - 1X : End (use support) - 1X : Lock (use support) - 1X : Buffer Tube (no support) - 2X: Cones (no support - print flat with channels on bottom for easy part removal) - 4X: Roller Ends (use support) Hardware: * 4X : Threaded Rods - 1 ft, 5/16"-24 - https://www.mcmaster.com/90032a051 * 4X : Hex Head Screw - 1-1/4", 5/16"-24 - https://www.mcmaster.com/92198a306 * 1X : Hex Head Screw - 1-3/4", 5/16"-24 - https://www.mcmaster.com/92198a308 * 2X : Wingnut - 5/16"-24 - https://www.mcmaster.com/92001a331 * 19X : Hex Nut - 5/16"-24 - https://www.mcmaster.com/91845a115 * 1X : Phillips Head Screw - 45mm, M3 - https://www.mcmaster.com/90116a186 * 2X : Hex Nut - M3 - https://www.mcmaster.com/94150a325 * 2X : Aluminum Hex Bar - 1 ft, 7mm - https://www.mcmaster.com/8252t31 * 1X : Acrylic Tube - 6 ft, 1" OD, 7/8" ID - https://www.mcmaster.com/8532k21 * 5X : Skateboard bearing - 8x22x7mm, including washers - https://smile.amazon.com/dp/B07VH6XT6Z/ref=cm_sw_r_tw_dp_U_x_q8WBEbDF5A3BX Some cutting of materials to size is necessary, like the acrylic tubing, and possibly the hex bar. For long-term use, consider nylon locking nuts and/or lock-tite in areas that would benefit. On the other hand, a finger-tight configuration also has its convenience, but may require tightening now and then. Happy rolling!
