Summary

One 2x2 brick 1 unit height, compatible with Duplo.

Designed to avoid extra supports.

Version 1:
d-2x2x1-4pt-v1.stl had elephant foot;
Model outer radius 4.7 mm looks too free, must be 4.8 mm.
Model outer dimension 31.8 mm looks too big, must be 31.7 mm.

Version 2:
No elephant foot anymore, chamfer 0.5 mm was enougth.
Both ends are too tight: original Duplo has about 5 N, now the top connection needs 15 N, the bottom connection needs 10 N.
Model outer radius 4.8 mm looks too much, must be 4.72 mm.
Intern pop model radius must changed from 3.1 to 3.6 mm.
Bottom model connection length must be changed from 25.2 mm to 25.4 mm.

Version 3:
Works just fine! 5-8 N to place on original Duplo.
