The blocks are 2x3x9 cm.

Also included is a storage box that holds 42 blocks (7x2x3 blocks) and a lid. The lid has little ventilation holes for easier fit.

Everything is printed in Prusament PLA in the .3 mm draft setting with 10% infill for quick print. All parameters may of course be adjusted as desired.

Recommend printing the box and lid with a brim.
