This is the very first model I have made that I think could be of use for other people :)
You can insert a standard printing paper sheet (A4) into the slit and use this as your calendar
My printer (Ender 5 pro) does not have tight enough tolerances so I have to cut off 2-3 mm off the paper for it to fit in but it does not really bother me and if you printer is accurate you should not have to do this
I have included the top and bottom part as well as a version you can print in 4 parts and then glue together if you have a 235mm bed like me. If you would like it in more parts you can send me a message and I can do a version that fits your bed size and add it to the files on this post :)
Print Parameters:
0.12mm layers
100% infill
4 walls
Edit: Added a hook to the files to mount on the wall
