STL switchable task list

If you're looking for a little visible reminder of things that need to be done this might be the model for you.

The list comes as a set of 2, 4, 6 exchangeable tasks. I am using a strong double sided tape to glue it to the wall.

The task holders are taken from my https://www.printables.com/model/1210946-atd-air-traffic-todo-list - I know I am too much into todo lists.

Currently all my parts are printed in PLA, even the springs that move the sliders into place.  As the springs are not deformed in the two home positions there should be no material fatigue.

Most parts should be selfexplanatory.

You'll need a base (2, 4 or 6), the fitting number of springs and sliders, one switch lid per 2 task positions - they hold all the parts (spring, slider, insert) in place. 

Print two inserts per task position in the color you want to show when the slider is moved (no multi-color printer required). 

The ATD task holders slide in the slots from the side so tasks can be swapped easily when needed. In my ATD model you'll also find utilities like the task reservoir gridfinity bin that is shown in one of the images.

Update 2025-11-23 : added a task blank if you want to add printed text on your own. 

Update 2026-03-10 : The "STL switch lid" should be flipped on the back before printing.
