A simple part to visualise the rotation of the direct drive extruder on the Ender 3 V3 SE.
No magnets required, simply print and push fit.
I printed it in PETG, but would've probably come out better with PLA.
The author remixed this model.
Added 5mm ID / 8mm OD cylinder w/ hole for push fit onto Ender 3 V3 SE.
