Universal Joint

thingiverse

Construct a desktop universal joint by following these steps: First, print all parts from ABS with .2mm layers (4 forks, 2 blocks, an intermediate shaft, a crank, 2 long pivot pins, 4 short pivot pins, a crank shaft, a drive shaft, and a frame). Ensure a tight fit or glue the pieces together for best results. Start by gluing the intermediate shaft in the bottom hole on two forks, ensuring their faces are parallel. Next, attach the drive shaft to the bottom hole of the third fork. Then, affix the crank onto the end of the crank shaft and slide this assembly through a frame hole before attaching the fourth fork with glue. Finally, secure the blocks in the forks using long and short pivot pins. Your universal joint is now ready to spin and enjoy!
