Idea from video by Spyker Workshop to give the fan under the printer a little easier access to airflow.
This update is for a foot pad that allows for leveling of the printer. As shown in the photos you will need some additional hardware. M6 Bolts and Nuts. Lengths of 20-25 or even 30mm will work. Ideally a half nut to use as the brake. Also ideally a hex head bolt though you can use a nut as shown on a round head bolt.
