I made this project with the objective of making a functional attendance and lunch count system that my students would be able to customize.

My lesson idea:

My students will add text to the raised area of the blank plaques using tinkercad, and we will print them in a color of their choice. 

Printing:

I made all of the different colored areas different heights on the plaque so the print can be paused for color swapping. I used a Bambu with an AMS for my test prints, but pausing and swapping filament at 5.2mm and 10.2mm will give roughly the same effect. 

Assembly:

The plaques have holes for 6x3mm magnets to be glued in. I originally printed the pegs without magnets, but they slide very easily. After testing with my class, I might reprint the second peg option which includes holes for the same magnets. 

Revision 1:

Peg base thickened for more resistance.

Revision 2:

Added an alternate version which uses an insert. This should save filament the next time I print a class set. Each trimester, the students will be given a blank insert instead of the entire tracker strip to customize. Check out the cover photo to see revision 2 in action!

Also added a bottom section to give it a finished look.
