Task Strips
thingiverse
Based on flight strips used by air traffic controllers, task strips let you keep track of what you're doing right now and what's coming up next. Once you've completed a task or run out of time, slide it out from the bottom and pop it back into your queue or rub the task off and add it to the pile waiting to be reused again. Printed in three parts, just in case one failed as I'm breaking in a new printer, I used brims on mine but if you know your printer is stable, you can get away without them easily. The lollipop sticks are trimmed to size using a pair of wire cutters, and though I'm currently using a pencil, I'm thinking of painting them with whiteboard paint and using drywipe markers in the future unless this works well then I won't bother at all.
