Should work on other similar feet of diameter 30mm. Put the extender under case feet and gain 20mm height for better airflow.

I started with D1 and then played with different shapes to change the look. D3 and D4 use less filament due to its slimmer profile.

As I have printed a lot of D1, I won't be printing out the other designs, as only the external wall profile has changed. Share your makes and your impressions!
