Universal Joint for 13mm & 16mm Tubing

thingiverse

I required a universal joint for the trolling motor tiller handle extension in a hurry, but couldn't find one on Thingiverse. I therefore remodeled the u-joint design found in the kayak rudder setup published by @LoboCNC. My long-term plan is to remix the rudder assembly for use on my canoe and possibly incorporate a decent-sized stepper and/or gear-reduction for an electronically controlled (steered) rudder. The spider will attach to the two u-joint parts using 3mm screws, approximately 20mm in length, and 3mm nuts. I advise printing the spider at its current orientation for maximum strength. Pictures will be uploaded soon - I'm heading out to the lake tomorrow and still need to print the "spider".
