I needed a way to keep my sanding strips i use everyday at work organized and identified. I created this tray to hold 1 inch (25mm) sandpaper strips with multiple grit sizes. the slots keep the sandpaper from collecting dust/debris that could affect the work your involved in. The tray was split into 2 pieces to fit the my Bambu X1C build volume. i also added the non cut file for those that have bigger plate sizes.

I simply superglued the 2 halves together to join them.
