Simple Parametric Tray

A simple tray with customizable dimensions and support for rubber feet or magnets on the bottom. Want a magnetic box in a similar style? Check out my parametric magnetic box!

Customization

Length, Width, Depth

The dimensions of the tray interior.

Wall Thickness

Thickness of the walls and size of various chamfers/fillets. The bottom of the tray will have the foot inset added on top of this value to account for the feet.

Foot Diameter/Inset

Dimensions of the rubber or magnetic feet. The inset controls how deep the cutout for the feet will be.

Corner Radius

How rounded the corners of the tray are. Mostly an aesthetic choice.

Tolerance

Offset added to the insets for the feet. Default is 0.2mm.

Printing

Most standard profiles with a 0.2mm layer height should work just fine. Two or more wall loops and at least 15% infill of your choice depending on desired strength. The pre-built STL files are designed with a 0.2mm tolerance added to the magnet/foot holes.

The cutouts for the feet may affect bed adhesion, especially with filaments prone to warping such as ASA/ABS. I have inset them quite a bit to mitigate this but a brim may still be required depending on your setup and material.

There are no fine details on the tray that should be problematic with thicker layers/nozzles. Though you may need to adjust the wall thickness for anything larger than 0.6mm.

Assembly

The pre-built STL files expect 10mm rubber feet. Magnets of the same size should work but may be excessive. The foot diameter and inset may be customized in the included F3D file.

The 10mm adhesive feet from this pack or these magnets work pretty well. TPU feet technically work but I found they act more as bumpers and provide very little grip on most surfaces.
