This model is a reinforced version compared to my original model.
Important:
Please check if your profile has tongue (compare my 3d models for that) if it looks exactly like the one in the sketch below, take the standard one.
0.2mm tolerance for the mounting of the profile.
There are 2 versions. The version without bottom can be used dynamic along the profile. The version with bottom logically only at the end of the profile
As I do a lot with 20x20 profiles, you may be also like some of my other 20x20 projects. Find them here: https://www.printables.com/de/@extrawitz_1031389/collections/843219
