This model attaches with a compliant flexure to the edge of a standard baking tray. The only requirement is that the rounded edge of the tray has a diameter of 0.3" (7.6mm). It will provide a stable surface for adding labels from a label printer.
As a hobbyist, using these trays on a larger wheeled baking rack makes for a very efficient storage solution.
When printing, stand vertically. Supports are not required, however a raft or brim may be needed, modeled in Solidworks.
The author marked this model as their own original creation.
