Altoids Tin Horizontal Divider

thingiverse

Simple horizontal dividers for organizing an altoids tin. They are a snug fit so the best way to insert them is to place them into the tin at an angle and then rock them into place bending the main wall slightly. Once they're straight they should stay in place while still being able to be moved. The "fins" are 20mm by default but you could cut them with scissors to make them fit closer together if needed.
