JBV creative sells a nice counter model here: https://jbvcreative.com/collections/stl-downloads/products/the-mechanical-counter

This model is stand that you can place the counter on (this is not possible without it since some gears are sticking out on the bottom).

The part cannot be printed without support, I printed it upside down.

The actual counter shown in the images is not part of the model, you can purchase the files at the link above.
