All footings come in two parts, one basic footing and one screw to adjust the height. The screw has a M15x20 mm thread so height adjustment can be done around 15 mm. You will also need a 4mm screw to attach the foot to your furniture (4x25 should work most of the time).
Pictures show the two pattern variants, there is one plain model as .stl too.

For stability I recommend printing with at least 5 perimeters. 0.2 mm layer, 10% Infill in PLA already gives sturdy results. Swich to PETG or ASA for more durable prints or use thinner layers. The thread is the crucial part, so increasing the infill won't help, 10% to 15% should be fine.
