The part is printed from PLA material due to its hardness and printing accuracy. 

I used 2020 from Fysetc for the construction of profiles, where I measured the width of the profile 19.8mm. That's why I made a second option for a 20.0mm profile if you have different profiles than I do. 

The part is printed with a minimum tolerance, therefore, before using it, it is necessary to "walk out" a little in order to remove possible protrusions and small irregularities that arise during printing.
