So, I’m making a fully customizable calendar in OpenSCAD with the following features:

  • correct columns for every date - uses an algorithm to calculate the correct day of the week for any date, you just change the year and the calendar is correct
  • fully translatable
  • supports custom holidays
  • supports both MMU/AMS and single extruder (with the help of M600 or similar)

Planned features:

  • configurable holes for magnets or holes for hanging the calendar
  • configurable first day of the week

I can share the SCAD file, though beware it’s a work in progress and I haven’t test printed it yet.
