170 mm 3D-Printed lazy susan Bearing (PLA + Steel Balls, 10 kg Load) · 模型 216490
This is a functional 3D-printed ball bearing designed for light-duty applications and prototyping. Despite being made with PLA plates and standard 8mm steel balls, it achieves impressive performance. 🔹 Track diameter: 170 mm 🔹 Total weight: <340 g (including steel balls) 🔹 Tested load capacity: 10 kg (rotates smoothly under load) 🔹️M4 screw holes for installation and mechanical project integration 🔹 Design notes: Track includes a clearance gap (should not be 100% filled with balls) for smooth operation Tight-fit insertion holes secure the balls permanently once assembled Optimized for strength and durability within PLA printing limits This design demonstrates how far rapid prototyping with affordable materials can be pushed when combined with careful geometry and tolerancing. Intended use: Educational purposes Prototyping Light-duty applications where a low-cost, lightweight bearing is acceptable Included files: STL files for direct 3D printing SLDPRT files for CAD modifications 📸 Media provided: Load test under 10 kg Exploded view and orthographic CAD renders Video demo of assembly + testing: https://www.youtube.com/playlist?list=PLk50dGNV-r8zn3zW4w26Ig0xBCpIFNThr 👉 If you download and try it, I’d love to hear your results and feedback.
