This is a cup riser stand the De'Longhi Magnifica S espresso machine I made as our usual are small and sited a bit too low for our liking even with the “machine's nozzles” set to the lowest position.

This is a 20 mm riser with 5 mm post to fit in on the tray so it doesn't move from the machine's vibration.

Dimensions: 75 × 75 × 25 mm

You could also use your slicer's size tool to change the height (this will change the posts' height, so maybe you should probably split the object into 2 then change the height)
