Modular Rods for Rostock (100mm increments)

thingiverse

I am attempting to extend modular Rostock delta push rods for a larger-than-standard Rostock design. To accomplish this, I needed to create 300mm center-to-center configurations that could be accommodated within a standard 6" (150mm) print area. Each section added 100mm to the total length; therefore, it is advisable to check and adjust connecting screws for optimal results. The M3x10 rod utilized here would have benefited from an additional 2mm in length, namely, M3x12. In a larger format build of this type, the push rods could conceivably be extended up to 400mm or 500mm but these were deemed somewhat too flexible. Consequently, it was determined that these will be replaced with carbon fiber tubes along with Traxxas 1942 ball connectors when such replacements become necessary. It is hoped that perhaps others will find this solution useful. This specific design builds on the earlier derivative from Asger's half-rods and further derives from a sivar2311 half-rod model. These designs will remain compatible with either, providing they need to be extended to approximately 350mm total length. By using only the 'end' sections, a resulting delta push rod measuring 200mm center-to-center is created. Adding one 'mid' component yields an increase in size up to 300mm and another mid section results in an increased size of 400mm; once again these are calculated center-to-center as expected by most firmware setups (specifically using Marlin in configuration.h). Consequently, the rod lengths in question end up longer overall.
