Flat Axles For Filament Spool Winder

Simple horizontal cuts on the axles for flat printing with no supports. I also created a 128mm solid axle to hold the worm gear to replace the 39mm and 88mm axles. The original design wobbled a bit when driving the 60 tooth filament guide gear. This is a solid shaft through both bearings. Simply superglue the worm gear in the right place. The worm gear is remodeled with a hole instead of hexagon to slip over the 128mm shaft. I printed it with a .05mm xy hole compensation to fit smoothly over the shaft. 3mf project file provided with all the axles and worm gear. 

Update - added .stls for the models. It's a single stl for all the parts. You can split them into objects on the plate.
