Potters use texture sheets to apply a pattern to clay. You can smash a clay sheet onto it. You can roll a coil on it to make a coffee cup handle with the texture raping around the handle.

Here are 4 different simple texture sheets.

You can make your own designs, because  the OpenSCAD source code is included.

These models have one layer brim pads on each corner of the sheet to help it stick to the print bed. After printing, they are easy to remove. If you don't want them in your model, make new models using the OpenSCAD file with "support==false".
