PIP swivel container - parametric freecad project.

made it as a concept and it worked out pretty well.

Has build-in supports for top cutout.

inner diameter = 30 mm

inner height = 40 mm

tolerance = 0.4mm (tried 0.2 mm but it was too tight for my printer)

wall thickness = 2 mm (tried with 1-wall 0.8 mm and got failed geometry)
