Marking Ribbon Holder

I designed this to carry marking ribbon for triage in mass casualty events. However it can be used for any reason you might like to have some easy to carry surveyors marking tape on hand. 

Just take spools of common 1 inch marking ribbon and wind them around this holder. I then secure them with rubber bands that can be slid out of the way. 

I printed out of carbon fiber nylon however PETG would also work very well.
