A groundbreaking Kickstarter campaign for this revolutionary product is live: https://www.kickstarter.com/projects/522476987/filament-roller Make a generous contribution and receive a completed Filament Roller, showing your unwavering support. This innovative IR sensor and alarm detects the direction and speed of your filament spool with unprecedented accuracy. This cutting-edge sensor will sound an alert when your spool stops due to filament-jamming, nozzle-clogging, extruder-grinding, motor-stalling, or out-of-filament. This latest version boasts enhanced strength and ease of assembly. However, it features larger parts that can only be printed on larger 3D printers. Without the PCB, you can utilize this item like a standard low-friction filament roller. This roller can accommodate spools with widths ranging from 5-12cm. Required components: * 608 ball bearings (4 ea) * M3 x 12mm screws (14 ea) * M3 x 18mm screws (2 ea) * M3 nuts (16 ea) * M3 x 30mm screws (4 ea) * M5 washers (4 ea) * M5 nuts (4 ea) Optional components: * Filament Roller control board (1 ea) * Small rubber bands (16 ea) * Large rubber bands (4 ea) Printed parts: * Base(2-piece)-12x16cm (2 ea) AND Base(2-piece)-Connector * OR Base(single)-22x16cm (1 ea) * Pylon(PCB) (1 ea) * Pylon(PCB-spacer) (1 ea) * Pylon(No-PCB) (3 ea) * PylonFooter (4 ea) * Roller (4 ea) * SpoolTensioner (1 ea) Note: Special thanks to user projectstew for valuable suggestions on improving the first model. Print settings: * Printer: i3 Clone, Made-in-China * Rafts: No * Supports: No * Resolution: 0.3 * Infill: 20% Notes: These settings are merely recommendations. This is a functional print, and aesthetics are not a primary concern. Post-printing instructions: Base assembly: If your printer can handle printing a single 22x16cm base, then print it and no further assembly is required. If you're printing a 2-piece base, make two prints of the 12x16cm base. Print two base connectors and secure the two halves of the base together using M3 screws and nuts. PCB pylon: If you have a Filament Roller PCB, print: 1 Pylon(PCB), 1 PCB spacer, 1 Pylon footer. Using an 18mm M3 screw, attach the elements in the following order: PCB pylon - PCB - PCB spacer - Base - Pylon footer - M3 nuts Regular pylon (no PCB): For the other pylons, print three copies of: 1 Pylon (no-PCB), 1 pylon footer. Using a 12mm M3 screw, attach the elements in the following order: Pylon - Base - Pylon footer - M3 nuts Roller: Print four rollers. If you're using a Filament Roller PCB, paint at least one of them to block IR light. Spray paint, house paint, car paint, etc can all block IR light. After painting your roller(s), insert the 608 bearing using steady pressure. Attach the roller onto the pylon using an M5 screw, washer, and nut. If you have rubber bands, attach them to the roller to make a "tire" surface. Spool tensioner: To smooth out the feeding of the spool, insert the tensioner through the hub of the filament spool. Attach rubber bands from the spool to the M5 bolts on the pylons. This adds light tension to mitigate the "spring" force of the filament.
