Normal Distribution with Mean and Standard Deviation Markers

thingiverse

This was originally marked as a work in progress. However, the design has been redone completely, and can be found in the Remixed section, or here: http://www.thingiverse.com/thing:1463604 I also just tinkered around in NetFabb for a little and cut the design to be a little bit cleaner (and I think I removed the weird separation thing on the bottom). So there's a new .stl file I'd highly recommend trying, if you're printing this model. Though I'd still highly suggest one of my other ones. :) Also, apparently this one has a hole in the bottom... I will try to fix that. :| The standard normal distribution with approximate (one of them is off) markers for standard deviations from the mean. This is really just a prototype; I'm still working on perfecting the model, and making more to help demonstrate different things, and there's a bit of an issue where it prints kind of off on the bottom. I originally designed this to help assist with teaching someone visually impaired basic statistics, and the idea of the normal distribution as it is normally something taught visually. Post-Printing This is scaled up, but I don't remember the exact scale at the moment. I'll update when I do. Bottom of the print. I think when I was smoothing it out I accidentally did a cut with How I Designed This I started with the model of the normal distribution by ayoung. I removed the numbers and placed all the pieces together in a Chrome app called Design Something. I then added the divisive markers where the standard deviations are (though one of them, the +1s or +2s, is a bit off).
