Sanding wheel, Lamellar Grinder

cults3d

I needed to process some circular objects both internally and externally without manually doing it, which sounded like a chore. To make things easier, I printed out this small device, threaded a 3mm welding wire through it as an axis, and attached strips of sandpaper to its surface using glue. When combined with a drill, the workload significantly decreased, and sanding became a more manageable task. The drill and the device created enough airflow to blow against the target area, allowing me to dry-sand PLA without any issues. https://youtu.be/Hf2k6ma2GJU WARNING: I tested this setup for a while at low speed using a Dremel but ended up killing it in the process. It's unclear whether it was just bad luck or my 2.5-year-old Dremel couldn't handle the stress, so I wouldn't recommend trying it.
