Borrow a Tolerance: Mindset for Designers

Description: Did you know your assembly can be more accurate than your 3D printer? Let's deep-dive into precision designs, regardless of your printer. This is an educational video for designers to learn about borrowing features, material qualities, or geometry from common parts, ultimately enhancing their results in making reliable assemblies. I included these elements to explain the topic: 1) Useful components to "borrow" 2) CAD demonstration for geometry 3) Material Properties discussion with application 4) 3D designs, open source models 3) Mass Produced design Examples Online parts: Big shiny ball, 3/4 in ► https://amzn.to/3MuwqjL Small shiny ball, 3/8 in ► https://amzn.to/3TgkdmO Pink nylon ball, 0.43 in ► https://amzn.to/4e8DRsC Poly tube, 3/8 od ► https://amzn.to/3XaiTD9 CHAPTERS 0:00 about this topic 1:16 deigns in the wild 5:17 precise shaft alignment 8:39 ball bearings 12:11 runout, rotation 15:36 5 CONCEPTS for balls 19:09 borrow a SPRING 24:50 borrow TOUGHNESS 27:20 smoothness? 28:43 golf tee 30:08 what to add next?
