For the Rod I ended up printing that with 8 wall line count and a 40% infill only because I had concerns that the rod being so small in diameter may cause issues with heavier spools, but in all my original testing i was at a standard 2 wall line count and 20% infill and had no issues.\u003c\/p\u003e\n\u003cp\u003eFor all my printing i stuck with the .2mm layer height which was the goal of my remix.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch1 class=\"thing-component-header design how-i-designed-this\"\u003eHow I Designed This\u003c\/h1\u003e\n\u003cp class=\"detail-title\"\u003e\u003cstrong\u003eFirst Timer Alert\u003c\/strong\u003e\u003c\/p\u003e\n\u003cpre\u003e\u003ccode\u003e            \u003cdiv\u003e\u003cp\u003eSo I'm completely new to 3D printing and 3D design. I used the 3D Builder app on the Microsoft store. I was originally upset when I realized there's no easy way to do threading but when I looked at trying to use something like Fusion 360 it seemed a bit intimidating for a beginner. I just borrowed my father in law's calipers got some measurements and did a lot of tiny test prints analyzing single aspects of the print design part by part. I was originally going to have some sort of clamping system for the end of the rod to allow for the shaft to be placed and then locked somewhat, but after running into issues with the design and realizing the bulge added actually kept the bearings pretty secure I decided to scrap that entirely. For most of the print I just made the sections as cutouts and then from a larger cylinder subtracted the custom cutout from the barrel to get my part.\u003c\/p\u003e\u003c\/div\u003e            \u003cp class=\"detail-image\"\u003e\u003cimg src=\"https:\/\/makerworld.bblmw.com\/makerworld\/model\/DSM00000001210916\/design\/2025-03-15_s3fo0t3cb0wq.jpg\"\u003e\u003c\/p\u003e            \u003cp class=\"detail-caption\"\u003e\u003cstrong\u003eBearing Housing Design Iterations\u003c\/strong\u003e\u003c\/p\u003e                \u003cp class=\"detail-image\"\u003e\u003cimg src=\"https:\/\/makerworld.bblmw.com\/makerworld\/model\/DSM00000001210916\/design\/2025-03-15_g1akkt9ov1ua.jpg\"\u003e\u003c\/p\u003e            \u003cp class=\"detail-caption\"\u003e\u003cstrong\u003eBearing Rod Design Iterations\u003c\/strong\u003e\u003c\/p\u003e                \u003cp class=\"detail-image\"\u003e\u003cimg src=\"https:\/\/makerworld.bblmw.com\/makerworld\/model\/DSM00000001210916\/design\/2025-03-15_821m5g5qn7al.jpg\"\u003e\u003c\/p\u003e            \u003cp class=\"detail-caption\"\u003e\u003cstrong\u003eShaft Pushrod Clearance Example\u003c\/strong\u003e\u003c\/p\u003e                \u003cp class=\"detail-image\"\u003e\u003cimg src=\"https:\/\/makerworld.bblmw.com\/makerworld\/model\/DSM00000001210916\/design\/2025-03-15_fejbpn5mrjfu.jpg\"\u003e\u003c\/p\u003e            \u003cp class=\"detail-caption\"\u003e\u003cstrong\u003eBearing Fit Example\u003c\/strong\u003e\u003c\/p\u003e                \u003cp class=\"detail-image\"\u003e\u003cimg src=\"https:\/\/makerworld.bblmw.com\/makerworld\/model\/DSM00000001210916\/design\/2025-03-15_r5yfn6zh0ykw.png\"\u003e\u003c\/p\u003e\u003c\/code\u003e\u003c\/pre\u003e\n\u003c\/div\u003e\n\u003cp\u003eDesign by Jeymz on MakerWorld (license: BY-SA).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67444556464432,"sku":null,"price":7.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_84fce74e-ce3a-4aab-be5a-040a412338b1.png?v=1785802384","url":"https:\/\/mymadmanlab.com\/products\/ender-3-stock-spool-holder-with-bearings","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
