Traxxas 5247 to Carbon Tube Coupler With Compression Lock

thingiverse

This coupler was designed to attach Traxxas 5347 ball joints to 1/2" carbon fiber tubes for use on a large Delta-style 3D printer. The creator is using 24" long, 0.5" OD carbon fiber tubes for the effector arms and offers two STL files: one with small balls for support and another without. The coupler was created because the builder preferred an adjustable, maintainable design over using glue. To connect the component, print the part (suggested 50% infill or higher), break off the ball supports, clean loose plastic threads, insert the Traxxas shaft into the cone side of the sleeve, add an M4 bolt and washer through the hole, then secure with a nut. Slide in the carbon fiber tube and tighten compression tabs using an M3 bolt and nut, adding a thin silicone sleeve between the tab and tube for extra grip if needed. Repeat for all effector arms, adjusting length as necessary.
