TuMbler makers often are dealing with Glitter, Rhinestones etc. Having a tray to work on your tumbler that catches is important, but also the ability to easily add that material back into the container.

These trays were made with these guidelines:

Must be large as possible for a Bambu size printer

Must have a grate above

Must have a "plug" that can be used to sweep the media back into the bottle.

So this is what we came up with. I believe you can use these if you make tumblers... and I believe these can be sold on Etsy etc. pretty easily. This is a product already available... but the store bought ones are cheap, and meant to be a consumable.

Let me know if you have any questions or suggestions.
