Easy to print weekly calendar, it offers the possibility of storing everything you need to make your appointments in the practical drawer hidden in the base. The solid pins give you the opportunity to always keep your most important appointments of the week in sight. I RECOMMEND: THE PINS AND THE MONTH MARK MUST BE PRINTED WITH 100% INFILL, SO INCREASE THE NUMBER OF WALLS TO 20 AND YOU WILL HAVE NO PROBLEMS. Furthermore, the main body can be detached from the base and can be placed on any metal surface thanks to the special slots for the magnets in the rear part, the magnets I used are 5mm x 3mm in size. Plus you can use the same base for another version of the calendar, take a look here: https://makerworld.com/en/models/113697#profileId-122206
