Standard Normal Distribution with Two Standard Deviation Marks

thingiverse

The normal distribution with two channels on either side, just one and two standard deviations from the mean.\nI'm really sorry about those bad pictures, judging good lighting is not my thing. My other recent file should give a clear idea: http://www.thingiverse.com/thing:1381014\nPrint Settings\nPrinter Brand:\n LulzBot\n \n Printer:\n TAZ 4\n \n Rafts:\n Doesn't Matter\n \n Supports:\n No\n \n Resolution:\n .Unsure\n \n Infill:\n 20%\n \n Notes:\n Brim! Use a brim. Using Cura, I simply checked the Brim checkbox from the simple printing settings. It's probably 5mm.\nPost-Printing\nRemove Brim\n Once the print is complete, the brim will be stuck to the edges and some parts will fill the channels. Removing it with tweezers is quite easy.\nHow I Designed This\nSteps\n I remixed ayoung's "Normal distribution sliced to show "68-95-99.7 Rule"" model by removing numbers and splitting the pieces before sticking them all together.\nI then took this piece and used it to cut out a section from a (roughly) circumscribed rectangular prism. I then used that cut out on another rectangular prism of the same size to get back to a (now much smoother) curve piece.\nThen, I made a small rectangular prism (the dimensions of which I forgot) and copied it six times, then used it to slice the channels in the model for the markers (cut one body using another).
