Description
***New version available!***
Version 2 has been completely redesigned! The tabs that slide left and right have been given circular bases, which allows for much smoother movement. It has been working well in my class! Enjoy! The print file includes support blockers, and a pause for the insertion of magnets (8x3mm for the bigger pieces, 6x2.5mm for the sliders).
Original version:
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.
