The screenshot of my first slice is off to the left. The first iteration, with an inner diameter of 3 mm, was too small and didn&#8217;t fit onto the motor shaft, so I printed the next two iterations with diameters of 3.25 mm and 3.5 mm. The hub with a diameter of 3.25 fit almost perfectly, but it was just slightly too loose.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-483 alignright\" src=\"https:\/\/portfolio.wcu.edu\/habene1\/wp-content\/uploads\/sites\/1717\/2022\/12\/Untitled-PrusaSlicer-2.5.0-based-on-Slic3r-12_1_2022-9_26_21-PM-300x149.png\" alt=\"\" width=\"300\" height=\"149\" \/>So, I expanded the hub into a full wheel with an inner diameter of 3.2 and printed it. The slice for that is off to the right. Once this wheel was printed, it fit perfectly onto the motor shaft. It press fit onto the shaft and it doesn&#8217;t slip at all. The pictures of the printed hub and wheel on the motor can be seen below.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-484\" src=\"https:\/\/portfolio.wcu.edu\/habene1\/wp-content\/uploads\/sites\/1717\/2022\/12\/20221201_205817-292x300.jpg\" alt=\"\" width=\"292\" height=\"300\" \/> <img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-485\" src=\"https:\/\/portfolio.wcu.edu\/habene1\/wp-content\/uploads\/sites\/1717\/2022\/12\/20221201_205926-276x300.jpg\" alt=\"\" width=\"276\" height=\"300\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>For this assignment, I had to design a wheel to fit onto the mounting face of the motor.
