Punctuation Kit

Here is a nice little punctuation kit. I designed it in fusion 360, and really had no clue what I was doing.
Anyway, one of my practicums for my education degree was with a grade 4 class. One of the things that we did very frequently was a collective grammar exercise. With this in mind, I decided to make a punctuation kit for table groups. Each kit has commas, backwards commas, periods, the tops of question marks, and the top half of exclamation marks. These symbols can be combined to create most common punctuation, and they were designed with a little clip on the back that fits around a common drinking straw (print at 110% and they fit around a standard pencil). When doing grammar exercises, students can read an incorrect sentence on the board, clip the appropriate pieces of punctuation that would fix the sentence and hold them up.
