The previous model was redesigned because it was difficult to print with FDM. This model was scaled to 50%, but it was easy to print with an FDM printer. +Dec 3, 2020 Found a major problem, all files were changed, existing files were removed, and a strongspring version was added to make use of weaker materials as well. +Added thin version with weak strength. +Dec 4, 2020 The thin version has a bridge problem and has been redesigned. And I added the thin strongspring version.
