Cog for IKEA blind
thingiverse
This is a cog for a project involving being able to pull up a blind from IKEA. They use a string with spheres on it for pulling the blind up and down. This cog fits the spheres perfectly and is made to fit the rod of a stepper motor. The blind I am designing for is linked below. http://www.ikea.com/us/en/catalog/products/10309150/ Update I have now changed so that the center hole is straight through instead of stopping 2 mm from one side. Print Settings Printer: P3Steel Rafts: No Supports: Doesn't Matter Infill: 20 % Notes: Be sure to print with ABS or some other material that can withstand the pressure from the blind. At least 20 % infill is recommended.
