Hand Crank Centrifuge (Entry)

thingiverse

RemixChallenge This is my submission for the remix challenge and it is remix of the dremelfuge by cathalgarvey and this is a hand crank version of what he did. This prints in roughly 5 hours total and uses a 1:6 gear ratio to take your hand motion and turn it into a super fast centrifuge that could be used for various things without having to own a high power Dremel or other such devices. (Note: there are some included caps if you choose to use them they are not necessary but make it easier to spin the gears at high speeds) Print Settings Printer Brand: Tinkertine Studio Printer: Ditto + Rafts: No Supports: No Resolution: 300 microns is what i used Infill: 5 percent is plenty Notes: The Files are designed with fast printing in mind so don't worry to much and each separate part(not the caps) should take about an hour to print. Post-Printing light sanding on the gear shafts is nice and if you chose to print the caps they may need some light sanding to fit depending on your printer. Also make sure you clean any strings of plastic in the gears so it can spin freely. How I Designed This I used 123D Design and took the dremelfuge model and cut a square hole in it and proceeded to build the mechanism around that by making the gears first and then the base to hold all of the components together. I then took the models and did light clean up in mesh mixer.
