Summary

*Work in progress! Dimensions are not 100% perfect and some areas could be optimized for lower filament usage. Changes to support structures for heavier watches may be coming as well.

This is a four-post stackable watch tower for wrist watches. I got aggravated with the limited capacity relative to how much space watch boxes took up and decided to model a tower that could be as tall or short as you want.
With this you can expand as your number of watches grow. These are friction-fit pieces, so your printer needs to be dialed in to not run into clearance issues. If you have a looser printer you can adjust the dimensions up but 1/2-1% for the middle and top towers to allow the connecting posts to fit, or simply shim them down a little.

Feel free to tinker and re-upload revised versions of this!
