Some months ago I remembered a drawing tool I played with as a child, the Spirograph.  Searching local stores only resulted in a small, poor substitute in plastic, of the ones I remember. Thus the inspiration and the idea for this project grew. I have a background in fabricating Museum, Zoo and Nature Center exhibits. For 25 years I was asked to build the most amazing things. This project would be no problem.
The design in mind included;  #1) large enough to fill an 8.5 x 11 piece of paper,  #2) the holes would fit fine-tipped Sharpies,  #3) the “look” would be industrial gear-like,  #4) made of wood, not plastic,  #5) be durable considering children would use it.

My daughter would love this! I had one when I was a kid. Would you be willing to sell me the file CNC?

I know you don't like plastic but for people with vinyl cutters rather than CNCs, I'm wondering if something similar could be done by cutting gears out of some other material (vinyl cutter limitations would require it to be no more than roughly 1/8in thick, and no stiffer than cardboard).

Very nice but is there a chance you can post your CAD files?
Great instructable!

May have to try to make a set on my Sherline CNC...

BUT....
I don't see no examples of how good the Spirograph works!

Please have the children post some pictures of there artwork!

Could you attach the files you used! Vectors? Gcode?
Great inspirational project!

I agree with Greasetattoo though... examples... files...?

Pretty cool. I made some on my laser cutter with acrylic but not as nice as these...

I loved this "app" when younger...
May you consider to distribute abroad?!? I want one!!!

Great idea!

Do you have DXFs, or other CAD files, for the gears, that you would be willing to post?

Spirograms have always fascinated me, and you have created a really nice set of a size that can give you some really spectacular tracings.

You might want to try some oval tracks where the length is significantly greater than the width.

Some of the more interesting designs would be difficult to produce with machinery, but rather be done on an x-y plotter or similar computer graphics output device. For example slowly decreasing the radius of of one or both of the wheels for each incremental move of one wheel. I did some software that did that, but lost it when the plotter died.

Great work, and another justification to add to my pile for buying my own CNC router.

Also I noticed how you were setting your Z to 0000 you can get a tool set that works well with Mach3 on ebay for 20.00, or they are easy to make they are very handy when using different thickness material.It will set your bit to zero using Mach3 and you wont have to touch your router when zeroing out.

Nice work, take a look at my structable in the cnc section 0% dust brush for rotozip, I believe you can get the vac att. to fit your router this works so well I am able to run my machine in the house, that is when my wifes out anyway very nice work

I had a Spirograph when I was a kid. I loved it! I don't have the equipment to do this project - but the only thing I can think of to add would be some pictures of the designs that can be made with your project. It's possible that not everyone would know what this can do. (You want to make me one?)

Good job!
