this is the Bento lunch Box I have designed.

 The top of the box has a D20 logo on it.

The first files are the test fit pieces because I have not printed them myself.
If they are too small or too Big just adjust the scale in your slicer. when the test pieces fit then you can move on to the real prints with the correct settings.

if you need to convert the gcode file to a STL here is a website that can help.

ABS is used for the build of the Bento box and anything that says LID is the sealant between the layers and TPU is best for that.

you will have to smooth it when you are finished printing because it is a lunch box and bacteria will form between the layers so it must be smoothed. I recommend vapour smoothing. it is easily done with the ABS.
