All files are printable without supports.
With a well tuned printer, the parts click and hold in place without glue. But I would glue it anyway. Otherwise it is still possible to adjust the clearance or features within the 3D-files (fully adjustable with fusion 360 or Autodesk Inventor 2024 and newer).
I printed the parts in 0,16 mm layer height and 15% cubic infill without any problems.
I am looking forward to your makes and remixes!
