20 - Ball bearing oldham coupler

thingiverse

This coupler is a modified version of the original Tevo Tarantula Oldham design, utilizing 20 .177 airgun BBs as bearings to minimize its width while maintaining functionality. With an exterior dimension of 29.66mm square, this innovative coupler has been crafted to be as compact as possible. The lead nut mounting system is directly borrowed from the original Tevo Tarantula design, ensuring a seamless integration with existing components. This custom-built coupler is specifically engineered for use on the Tevo Tarantula Pro model. To assemble this coupler, you'll need to carefully file and sand the tabs and slots to achieve a precise fit. Patience is key here, as it's easier to remove excess material than to add more once it's been removed.
