Brush with travel case.
Originally intended as a beard grooming brush but it turned out to be a nice all around brush. Included in the print is a case for keeping the brush safe when traveling or when carrying it in a pocket, purse or bag.
The bristles are fairly stiff when printed in PLA.
The brush keeps up well while using it but the thin bristles break easy unless the brush is kept safe in the case. To store the brush put it in the case with the bristles facing the two ridges, this will keep it secured in the case.
Print the part with standard settings for PLA, the bridging seems to work well without any special settings.
Remove the brush from the case with, for example, a cutlery knife. No need to use a sharp knife for PLA as the bristles are easy to break free from the wall. Do small cuts from all directions and cut only a few strands at a time to avoid breaking the bristles.
It probably works well to print the brush in other materials.
Scaling the brush up is also an option if you need a larger brush for grooming a pet or some other use.
