I used this two svg files to make my model of bookend in Fusion 360 https://svgsilh.com/fr/image/1296104.html https://svgsilh.com/fr/image/2814846.html . I print it with variable infill (80% for the 10 first mm and after 15%)
In the v2 files the mouse's tail is thicker for a better impression
The author marked this model as their own original creation.
