Extensions you can install under the legs of the Mini Base upgrade. They raise the entire printer/base by 14 mm, allowing you to tuck some extra tools or gummy bears under the filament spool. They use the original foam pads; just peel them off of the legs, press the extension onto the leg, and replace the foam pad.

You will need to print four of these, one for each leg. Supports are not needed. If you use the included print file, it already includes the four feet you will need.

I printed these in two colors. In the pictures, the color changes at z = 3 mm. (The color change is not included in the print file.)

There are several free CAD programs you could use to adjust the height of the extensions for your needs; I used SketchUp to design these.
