Sheet Metal X carriage（use with printed parts）

First, thanks Ben Levi for his awesome project.This project is quite charming and it added so much pleasure to my life.

Personally I think produce belt_locker_plate requires some processing difficulty, and expensive(no offense).That's why I choose to use the sheet metal forming.
At first this parts has some belt_angel issue because 2.5mm metal is not high enough(showed in image made by Ben Levi).

And my immature plan is to add a 3D printed part "Thickness increaser", hope it will work fin
