Normal Distribution with Two Standard Deviation Marks

SummaryThe normal distribution with two channels in each side, at one and two standard deviations out from the mean. Sorry for the crappy pictures, I am really bad at judging good lighting. My other recent file should give a good reference point: http://www.thingiverse.com/thing:1381014Print SettingsPrinter Brand: LulzBotPrinter: TAZ 4Rafts: Doesn't MatterSupports: NoResolution: .5mmInfill: UnsureNotes: Brim! Use a brim. Using Cura, I just selected the Brim checkbox from the simple printing settings. I think it's 5mm.Post-PrintingRemove BrimOnce the print is done, the brim will be attache to the edges and some will fill the channels. Using tweezers to peel it off is quite easy.How I Designed ThisStepsRemixed ayoung's "Normal distribution sliced to show "68-95-99.7 Rule"" model by removing the numbers and splitting the pieces before sticking them all together. I then took this piece and used it to cut out a section from a (roughly) circumscribed rectangular prism. I then used this cut out on another rectangular prism of the same size to get back to a (now much smoother) curve piece. Then, I made a small rectangular prism (the dimensions of which I forget) and copied it six times, then used it to slice the channels in the model for the markers (cut one body using another).
