My Contribution
Originally, I was going to work on the assignment with Tomohiro Inoue of Kitakagaya, but our schedules suddenly became incompatible, so this discussion was cancelled. So this time I decided to work with a local instructor to advance the assignment.

2.Design and Assembly
2.0 frame
I purchased an aluminum frame from Misumi.
I inserted this into Fusion360 with 3D data.

- Fusion360
2.1 Stepping Motor
First, measure the parts to be used. This process is very important for design.
I designed the parts to attach the motor to the frame in Fusion360.
- try1
It worked, but I had to come up with another design because the motor heats up and could unravel the PLA.
- try2
This time I think I have created a simple yet good design!
2.2 Pulley (side without motor)
I think we have designed this one well.
2.3 assembly
The design is output and attached to the frame.
Install using TM3 T-nuts. Install the other side in the same manner.
Finally, the belt and wheels are attached to complete the process.
3.Plate
- disin(Fusion360)
I made a plate to put the plates on. Designed to allow for the installation of limit switches.
- 3D printing
Finish by filing the limit switch so that it can be easily turned on.
