the idea of a tear-off calendar seems particularly Dutch, however who knows what else it can be used for

A tear-off calendar (scheurkalender in dutch), is a thick 365/366 pages block of paper with something for every day on it. They come in different sizes, so a single model is difficult.

There are some other models available that may be suitable, but for me they didn't work or seemed so. So I made one that would work for the calendar that we have for 2025 (the Loesje kalender).

One way to commonly use a scheurkalender is to use the two holes to screw the calendar into the wall. This has several drawbacks: the holes may not be the same for next year's calendar, the top side isn't kept well together so you get issues with tearing off a page. And once you have the holes, you can't have the calendar anywhere else or choose not to have one. (BTW, the most common place to have a scheurkalender is in the toilet ;-)

The design I made is in three parts (you can choose which part to print in the customizer, as well as the sizes of various parts).

Things to note:

  • I had lots of warping issues when printing with PETG on a powder coated sheet, causing my mk4s to trigger a stuck filament detected action, when the warping part blocked the opening in the nozzle. (I have a suspicion that it may be my heatbed, or that it's just generally hard to print PETG)

  • Avoid printing with supports, or even a brim, because it will cause problems for the sliding together of the parts.

  • If you print the woodbase model (recommended, I didn't test the “stand” part)

  • You need mount_a, mount_b and either stand or woodbase.

  • for the mount_a part, you may want a smaller “holed” value, if you want to screw the thread of a bolt into the flesh of the printed part. Or bigger to pass through and screw a nut and washer on the back.

  • I've assumed a tapered head for the bolt (which I had laying around), you may need to tweak the scad file to fit a different type of bolt.

  • when screwing the woodbase into a small plank, be sure to pre-drill the hole, to prevent the wood from splitting.

  • the white “mount_a” on the picture is printed in PLA on bluetape covered printsheet.

  • You can print a “tray” to go with the calendar to hold the torn off pages, in case you want to keep them for a while.

BTW the rails should be the same as this model

PS After almost a year in service, it's still holding up fine. Of course I changed the wooden base from the piece of scrap wood to a bit nicer piece of scrap wood ;-)
