Because of the fine detail I found that slowing down the first layer to 10mm/s helped a lot. I also reduced the first layer acceleration to 400mm/s^2.
EDIT: I noticed the snaps were a lot stiffer in the Prusament Red, so I've added a second version for easier snapping.
EDIT 2: Added a Version 2 model. Snaps are slightly easier on the pivots, and I've made the holes larger for adding a string and hook.
I find that a max layer height of .2mm is necessary for the snaps to function well.
Using small side cutters works the best for freeing the parts.
The author marked this model as their own original creation.
