This vase mode modular tray can be printed in any size if you edit the OpenSCAD file. You can also change the scale of the waves. The texture stiffens the side walls and also reflects light into nice patterns.
The ones included here have matching textures so they can fit together as long as you orient them all in the same direction. (If you rotate 90 degrees they will mate together, but the edges will be misaligned.) The dimensions given are 80x40, 80x80 and 160x40.
Print in vase mode with 0.2 mm layer thickness.
The OpenSCAD code depends on the BOSL2 library which is at https://github.com/revarbat/BOSL2
The author marked this model as their own original creation.
