Snug Huggers

This shoe tree allows the printed form to not only hold the shape of a slipper, it creates contact with the interior of the slipper, something that is useful when the form is printed with Copper3D PLACTIVE AN1 filament. Laboratory studies confirm PLACTIVE rapidly reduces colony forming units of common microbes, including Staphylococcus aureus MRSA and Escherichia coli DH5α, achieving more than 99.99% elimination within 24 hours.

You can make a different sole part by outlining your foot instead of using the model part here or resize this sole part in modeling software before printing. After printing, the model can be cut with scissors to fit your slipper or similar shaped shoe.

I printed the models shown in the photograph with a 0.6 nozzle on a CR-10 mini printer.
