This week I modified Design 4 by making it shorter and adding divots. Design 4 was an 80-millimeter cylinder with cross divots on each end of the cylinder. It mildly worked but it was awkward to use. With the past few iterations, I have been thinking about making the tool help with holding/gripping on the elastic rather than making a tool that does the twisting and pulling hair through mechanism. I decided to put divots on the sides of the cylinder so that the elastic could sit in the tool and not move around as someone uses the tool to stretch the elastic open. I was luckily able to print my design this week and I hope to test it over the weekend. The project is due in one week and with the hopes of this design working, I will be making Design 6 my “final design” that I show at the Big Project Showcase and highlight on my website and potentially Thingiverse.
