Here you can find Bunny Low Poly Vase mode - a modified model of the bunicorn from von VoxInaudita.

With this modification you can print it in vase mode.

Depending on your scale, you should increase the line width and decrease the layer height. For big size you should change to a bigger nozzle diameter, too.

With a 0.4mm nozzle you usually can print a 0.7mm or also a 0.8mm line width. That makes more things printable and increase the stiffness.

Just slice it with higher width and check the forecast from the top and bottom side, if there are any gaps between the lines.

2022-10-15: Improved the model for better printing.

Would be happy to see your makes.
