This is a foot file that could be used to remove hard dead skin from your foot. Use this as any other foot file, this is a print in place that does not require any other hardware. This has two different types of surfaces that could be used to remove dead skin.

This does need a bit of support to make the handle, could have made the handle thicker but would be uncomfortable to hold.

I used 3 walls and 20% cubic infill with PLA, and it is strong enough to be used.
