I work in a warehouse.
There's a lot of distance to cover between destinations.

We use scooters, but scooters don't stand up well.

So, voila, the scooter hanger.

Print with support and relatively sturdy print settings (3 layer shell, >25% infill).

Be careful removing the support from the hooks, applying too much outward force will break them if printed with a standard FDM machine.

Use 2/4 screws depending on how heavy your scooter is.
