Have you ever wanted draw repeating geometric patterns at any time in any place?
No? Well, let's pretend you did...
This handheld print conveniently combines a drawing platform with a case for the gears and paper. It easily fits into a bag, pocket, or purse. As long as you have a pen, you're good to draw!
The base is designed with multiple levels. The bottom level holds the paper, the drawing gears, and, if you can find one, a small pen. The next level provides a flat, secure drawing surface; you can even make art while walking! The top level has the stationary gear teeth and holds the paper in place.
This kit is designed to use Post-It Notes as paper. It requires no paper cutting, and your finished pieces of art are already self-adhesive!
Almost any standard ballpoint pen can be used. A BIC pen was used for sizing, but the design works with every pen that I tested.
You'll need to print one top, middle, bottom, and latch. You can print as many gears as you want.
I added a new version of the top with 31 teeth (Top-V2.stl). It's untested, but should create more complex patterns.
For the middle layer, I suggest using 6 top/bottom layers and an infill of 25% at least. This will create a better drawing surface.
The hinge is simply a length of 1.75mm filament. Make sure to cut one end to a steep angle.
If the surface texture of the middle part is creating a texture in the drawing:
For the hinge assembly:
Make sure the entire case is snapped closed before drawing!
