After a post on Reddit/r/3DPrinting I had several people asking me for this .STL
This is part of a project I am working on to design and build an RC tank focusing on low cost and simplicity. The entire project is not yet complete and I plan on uploading everything once I have verified it is all functional.
This tank track design uses 6mm airsoft BBs as the hinge. This is much more functional that trying to print a hinge mechanism and much more cost effective than using bolts as the hinge as I have seen in many other designs. The concept of using ball bearings as hinges has a wide variety of applications in 3D printing and I encourage everyone to try and incorporate these type of creative solutions into their own designs.
NOTE: This is a PROTOTYPE and has yet to be tested on a fully functional RC tank.
