MOZA R9 (v1) - Nút nguồn bật từ phía trước (front extend)

It's quite difficult for me to reach the base back to push the power button, and I've been thinking about this problem for a long time, I wanted a simple and elegant solution. It's not quite there yet, but it works. 
It does not interfere if someone installs a display or phone on the base, or if is on a cooler installed. 
It is necessary to have a surface at the bottom that support the bottom of the base. 
You need an adhesive for the pivot point, where you can snap the rotating arm (knob). 
I was afraid of printing the base, but there was no problem, the printer solved the bridging easily. 
I was too lazy to print the rodend and glue on the end of the slider, I deformed it with a hot knife so that it could not be pulled forward.

As I looked online, this is only good for the R9(v1) for sure.
If anyone has an idea how the mechanics can be simpler, please let me know.

ps: Don't forget! If you push it long, you turn off the base.
