This thing can be used to pick up food crumbs, pet hair, lint, and (my personal favorite) little plastic shavings. This is my first attempt at drawing a curve on my Wacom tablet and using it in my design. Also my first time using QCad, which is pretty nice. This thing will remain a work in progress until it is printed and known working.

I believe all three pieces should fit on the build plate at once. Print them, put the roller on the bar, add glue to the square part at the end of the bar, and insert it into the handle.
Once the glue has dried, spiral some tape (with the sticky side out) around the roller.
Now roll it around on stuff and watch it clean up!
