Lego Arm A.B.S Holder

For this project, we used $11.41 worth of PLA and a metal dowel that costs $11.49, for a grand total of $22.90.

Both arms: $10.62

Both dowel caps:$0.79

Aluminum dowel: $11.49

Firstly, we started our sketch in fusion 360. We made a centre-oriented circle that was 45mm in diameter, to stop the dowel from falling out of the hands.

For the second step of the dowel caps, we finished the sketch and we extruded what we had and then added a second cylinder to fit into the pipe. This finished the first dowel cap.

To finish our dowel caps, we simply copy and pasted our first dowel cap and pasted it right next to it. This finished our STL, and we then sliced it in Prusa Slicer to prepare it for the print.

We started the arms the same way as the dowel caps, only we started on the horizontal "y" axis instead of the "x" axis we used for the dowel caps. This is simply because we wanted to print the arms on the horizontal plane, not the vertical. We then sketched and extruded a large cylinder, and then a smaller one on one of the faces.

We then sketched a circle that we extruded into a thin cylinder. We made a circle inside of it and bored a hole 54mm wide into it, and then cut a rectangle out of it so that we could remove the dowel freely. We attached this to the original cylinders, finishing our lego hand. We didn't copy and paste this one because the arm is too big to print two at a time.

We finished up by slicing and printing the hand.
