Ender 3 Metal Extruder spring spacer

thingiverse

I bought a metal extruder, but I wasn't thrilled with the screw method of securing the spring. The sleeve nests perfectly under the screw head and the cap snaps securely onto the threads at the other end (check out the photos). Initially, the first version of the cap featured a chamfer on top - it was included for reference purposes. In contrast, the latest version of the cap now boasts a smooth fillet instead.
