NASA CHAMP - ClickLock

Last crawled date: 2 years ago

ClickLock utilizes a variable radius cam with preload enhancing 'fingerlets' on the opposite mating face of the rail. The pin is pushed through both the BACK and CAMLEVER parts simultaneously, taking advantage of an interference fit to form a permanent subassembly, but requiring no tools. Once the BACK, PIN, and CAMLEVER parts are mated into a subassembly and mounted onto the rail, FRONT can be slid into place, now allowing sliding adjustment of the mated system along the length of the rail section. When in final position, the assembly is locked in place by rotating CAMLEVER 90 degrees into its click-lock position.

The parts themselves are printable on any basic FDM machine with no support material required. The sample parts for my video were printed on a Stratasys Dimension 1200ES, which I felt was likely a closer match to the build quality and capability of the MADEINSPACE printer.

Total weight of the finished assembly, as printed, was 60g, using the 'sparse-high density' setting of the Stratasys. In my experience, this equates roughly to a 50% infill density on hobby-level FDM printers like a Makerbot 2X.
