7 Ball Bearing Keychain

thingiverse

Added a hole for a keychain ring. Great model to print in high resolution, making it perfect as a gift for friends and family. The dimensions are impressive: an external diameter of 30mm and a height of 8.4mm. Feel free to scale the design as you see fit - I scaled the white version in the picture to 25mm external, but you can experiment with different sizes. Printed using Simplify 3D, this model requires support to print successfully. With a layer thickness of 0.15mm and a nozzle diameter of 0.3mm, it's no surprise that print time is approximately 40 minutes. I used my Minibot 120 3D Printer from Brazil to create this design, and I'm excited to share the updated file with you - Keychain_Axis_8mm.STL. Alternatively, I've designed an 8mm axis for fixing the keychain ring, allowing you to print a standard 30mm ball bearing instead of my remixed version. The result is a more pleasant rolling experience when handling the ball bearing. Thanks for your interest in this project!
