See Through Rotating Calendar

GeneralThis is your new workout device: 2, 3 or 4 clicks every day, and you are done!Choise of 4 languages: English, French, German and Dutch.Any order of the rings can be chosen.A wide and small blank ring is added for use with 10 stickers of your own.Designed in Tinkercad.Dimensions: 98 x 52 x 57 mm.Weight: 0.09 kg. ScalingScaling down is possible to 80% (tested). At 80% the rings run a bit tightly. For a really smooth operation, the rings (not the other parts!) should be scaled down to 81% over the X- and Y-axis, and 80% over the Z-axis. PrintingI printed the model on a Prusa MINI, with PLA+ filament, layer height 0.15 mm. Slicing in PrusaSlicer.Avoid elephant foot and over-extrusion.Carefully remove the support material from the cores (A2, A4, A6, A8). Make sure both tongues of the cores can move freely. AssemblyAssembly in alphabetical order (A1 → A10).The calendar is glued together. I use Hard Plastic Glue.The rings can be assembled in any order.For assembled and exploded views,
