The model
The ten red rings are printed nested in one piece. Each ring can be pulled 8.5 mm out of the next larger one; then it rests with two bands on the 5.6° cone of the outer ring and wedges. If the wedging is ever not enough, a stop bead with 0.67 mm overlap keeps the rings together; downwards, a foot on the outer ring holds the inner one.
The white fur trim is pushed over the largest ring from above and snaps behind six small lugs. The white pompom sits in the tip with four spreading tongues. This makes the hat two-colored without the printer having to change colors.
The extension is calculated for all nine ring pairs in 12 positions each; in the print position the rings have at least 0.42 mm of clearance.
