Hi!
What's this?
This is a hand cranked drawing machine inspired on some Spiro-drawing machines i've seen recently.
Didn't found anything fully printable so i decided to make my own version.
Why i love this machine?
100% printable!. Except for markers and paper sheets :)
Hand cranked! But may be easy to plug some kind of DC motor.
NO supports at all. I hate supports
Fun and addictive. Those gears, loops and mechanics are highly addictive (at least for me)
Surprises inside. Explore with gears, combinations and you'll find some suprising patterns. Or found ugly and messy drawings :P
What i'm downloading?
ZIP file with all the STL's Many STL files so uploaded as a ZIP with files organized in folders. Includes 3 Plates and a complete set of gears.
PDF assembly guide. Step by step assembly process with pictures and some tips. Please read before asking on comments.
Hope you enjoy printing, assembling an drawing this one!!
Have fun!!
Tested with this resolution: 0.3 for structure, guides and washers, 0.2 for screws and nuts, 0.25 for gears and plates. Using low infill (10-20%) in gear and plates, and 50% in bolts and nuts. Used a horizontal expansion of -0.15 in plates for a smoother engage. Also used a -0.2 Horizontal expansion in crank and pins for penholder guides to avoid sanding and get a good insertion on gear holes.
