Pepper Mill/Grinder

8" Pepper mill/grinder housing to be used in conjunction with pepper grinder mechanism found here: http://www.amazon.com/Peppermill-Grinding-Mechanism-Shaft-Woodturning/dp/B00A6YFY4C/ref=sr_1_7?ie=UTF8&qid=1386199915&sr=8-7&keywords=pepper+grinder+kit+8. I was going to buy one or make one out of wood but decided this would be a way to show the utility of a 3D printer. If only the grinder mechanism didn't cost so much because I only used ~$6.75 in material cost. I printed the object on my Ultimaker 1 in ColorFabb XT but PLA would work fine too. This is my first attempt at this grinder and I am sure it could be optimized to look better, use less material, and probably function better. I included the SolidWorks part files so take it and make some better derivations! Instructions Printed in ColorFabb XT material on my Ultimaker 1 with the following print settings: Layer Height - 0.2mm Shell Thickness - 1.2mm Bottom/Top Thickness - 1mm Fill Density - 20% Print Speed - 50mm/s Print Temperature - 240C Orient the designs so the top part is standing on its top (where there is the largest fillet). The bottom part should stand on its top (where there are two cylinders to start). The picture in the gallery should explain the orientation if this is unclear. No support or scaling should be needed and it should work well in PLA (just lower the temp to ~215C at the same speed). The shell thickness is important because the screw holes are designed to be threaded into (so you need 1+mm of material for the thread engagement). This print took a while (10hrs) but I am sure someone can come up with either a more efficient design or push up the temperature and speed to print faster. Update 1: After printing, everything works great. It could stand to be just a few mm shorter in its overall length just so the coarse grind setting has a few more threads engaged on the top nut. Scaling down in the Z direction should work. Update 2: I re-sized the original file and reduce the Pepper Grinder Base height by ~2.5mm which should solve the issue noted in Update 1.
