I designed this block calendar specifically for people with impaired vision as well as dementia patients. Everything but the stand is printed face down with a filament colour change on the fifth layer.I used an Ender 3 S1 3D printer with these standard settings:Printed with PLA @ 0.2mm with 15% infill and a colour change at the 5th layer.Please see exploded views of Number and Day Blocks for assembly.The Month cards just slide into the bottom of the stand with the Day and Number blocks on top.
