Long story short, my library's printer broke from a class before the worker got to mine. I test printed fschuler's out today at a local makerspace that I discovered. I'm still going to print your chest piece out and probably the under part where you fused the side tabs in. Your pics here don't show that version, did you decide not to use it or you were satisfied with what you already printed?
This is cool but I would only be interested in a backpack piece that has a CW slot on it so that Swoop can be positioned as a backpack. But, cool.
