thingiverse

A customisable spool that mounts to Pololu motor hubs is available. It has been tested with Pololu Part No 1999, featuring a 6mm shaft and M3 screws, as well as Pololu Part No 2673, a 5mm shaft scooter mount with M3 screws. Revision 2.2 from August 19, 2015 indicates that the String_Diameter has been made variable for customizer thanks to weswitt's suggestion. Drawings suggest it may also fit part numbers: 1078 (a 3mm shaft with #4-40 screws), 1079 (a 3mm shaft with #2-56 screws), 1081 (a 4mm shaft with #4-40 screws), 1083 (a 6mm shaft with #4-40 screws), 1203 (a 5mm shaft with #4-40 screws), 1993 (a 1/4" shaft with #4-40 screws), 1994 (a 1/4" shaft with M3 screws), 1996 (a 3mm shaft with M3 screws), 1997 (a 4mm shaft with M3 screws), 1998 (a 5mm shaft with M3 screws), 2672 (a 4mm shaft scooter mount with M3 screws), 2674 (a 6mm shaft scooter mount with M3 screws), and 2675 (a 1/4" shaft scooter mount with M3 screws). Two holes with strain relief are provided to attach a string or wire. A nut or similar can be tied to the string, or a knot made in it to prevent it from pulling through. Requests for more features should be made by commenting below. Dimensions for customizing the spool include: 1) Radius of the spool from the center to the flat section (not including top and bottom flanges). 2) Width of spool from top flange to bottom, not including flanges. Both dimensions are in millimeters. The flanges are always 5mm wide/high with a 2mm rim on top and bottom. Recommend a 'High' Polygon count unless your spool is large.
