Bambu spool winding insert

Many of the inserts for Bambu reusable spools have one flaw or another that makes winding filament onto them a bit of a nightmare. Either the insert has poor tolerances leading it to slide all over the spool, or the release from the insert causes kinks in the filament that get caught in the AMS primary or secondary feeders, the AMS buffer, or directly at the extruder. on top of these problems, many of the available inserts also place the filament holes to far from the inside face of the spool leading to a lot of slop in winding that only cascades with each layer. Finally, all of the above create an overall sloppy wind on a spool that can impact accurate readings with gauges that measure remaining filament accurately. Worse yet, these winding issues can cause filament to seat against the inner faces of the spool that can push the sides of the spool out with each additional layer when neat and tightly winding spools. Enter the Sidewinder spool insert! I designed the Sidewinder insert so
