Ratchet Strap Holder
Created my own version in an attempt to get it use less material and print faster. Based on my Cura settings I was able to shave about an hour off the print time and 2-3 meters of material. Still easily fits a 15 foot strap. I also added a clip, so the two parts are held together when stored.
Update 3/26/19 - edited the clip to snap together better.
