Paper Towel Paint Brush
This is a paint brush made in sketchup. It includes a plug to secure a square of paper towel or other material.
SKETCHUP FILE INCLUDED
Fixed in Netfabb, scale down to your specific needs.
Prints without supports at the two sizes I tried. Print out the one piece print and clean the two pieces. Place the plug in the center of a paper towel square, wrap it, twist and then insert plug into handle. The bigger the square, the longer the brush tip. You can cut the brush tip at any angle to fit the task.
